! HISTORY:
!
!  265  The help for the /STREAM:[CARRIAGE_CONTROL:n|LINE_FEED:n] switch should
!       specify "maximum record size" (like /VARIABLE) not "record size"  (like
!       /FIXED).
!       Gregory A. Scott  10-Jul-86
!
!  262  Delete module DIUCMD.R36, moving defs as needed to DIUCOMMAND.
!       Gregory A. Scott  7-Jul-86
!
!  260  Commands using a time of "/AFTER:13-jun-95 13:13" didn't parse.
!       Gregory A. Scott 7-Jul-86
!
!  253  Library COMAND is now DIUCMD and PATPORTAL is now DIUPATPORTAL.
!       Gregory A. Scott 1-Jul-86
!
!  252	Remove library of CONDIT.
!	Sandy Clemens  1-Jul-86
!
!  246  Remove edit  245.  Add  /LIBOL:n  switch to  read  the files  that  are
!       written with RECORDING  MODE IS BINARY  with mixed-mode data.   Default
!       the /VFC switch to 2.
!       Gregory A. Scott 27-Jul-86
!
!  245	Make /IMAGE legal for  the input file for  reading TOPS-20 COBOL  files
!       with RECORDING  MODE IS  BINARY with  mixed-mode ASCII  data (which  is
!       ASCII text mixed with numeric data; fixed and or floating point).
!       Gregory A. Scott 26-Jul-86
!
!  234  Change library of RMSUSR to RMSINT.
!       Gregory A. Scott 17-Jul-86
!
!  232  Initialize patpar_warn to zero in INIT_REQUEST.
!       Sandy Clemens  16-Jun-86
!
!  230  Access control  string  that  didn't  specify  an  account  copied  the
!       password over as the account in ST_UPA routine.
!       Gregory A. Scott 12-Jun-86
!
!  220  RENAME should only  allow one input  filespec.  APPEND takes  different
!       switches than COPY  (e.g. no /IMAGE  and nothing but  /RMS:SEQUENTIAL).
!       Again make wildcards illegal for destination side of APPEND.
!       Gregory A. Scott 6-Jun-86
!
!  217  An illegal  destination  filespec  (like specifying  wildcards  on  the
!       resulted in "File not found" faked error message from DSTFIL.  Edit 215
!       caused a bug in the SHOW  QUEUE /switch parse tables to appear.   Allow
!       wildcards in  destination  to  APPEND  command  again.   Remove  APPEND
!       specific switches (/NEW/NONEW/OLD),  since the COPY  command does  /NEW
!       and the APPEND command does /OLD.  Remove all extra parse tables and so
!       on associated with the differences between APPEND and COPY.
!       Gregory A. Scott 5-Jun-86
!
!  216  Default of /OLD in the APPEND command should  set  the  CIF  bit rather
!       than clearing it.  Turn  off parse only bit  on output side of  APPEND.
!       Make p_src and p_dst GLOBAL so that DEF$REQUEST can use them.
!       Gregory A. Scott 4-Jun-86
!
!  215  Change IP_LIST call to SHOQUE.
!       Gregory A. Scott 3-Jun-86
!
!  214  Add routine SH_QUEUE and have the SHOW QUEUE routine call it.   Default
!       the destination switch  of /OLD on  the APPEND command  in the  REQUEST
!       routine.
!       Gregory A. Scott 3-Jun-86
!
!  211  Put a CMCFM before the destination file parse in the SUBMIT  and  PRINT
!       commands (so that we don't always hallucinate the  default  file name).
!       Allow multiple sources on the SUBMIT command.  Only write the $ETG  for
!       the destination filespec buffer if it is non-empty.
!       Gregory A. Scott 29-May-86
!
!  207  The /[NO]CONTIGUOUS switch could be typed to the input file.
!       Gregory A. Scott 27-May-86
!
!  206  Source remote filespec followed by a local filespec got SRCFIL confused
!       because sflags[F_NODE] wasn't reset in PRE_INPUT.
!       Gregory A. Scott 27-May-86
!
!  204  Allow HELP  topics to  include /switch,  add default  topic DIU.   Only
!       allow the /NOAFTER and /NODEADLINE switches from the MODIFY command.
!       Gregory A. Scott 24-May-86
!
!  203  Add macro  $TTY_FAO  which prints  a  FAOed message  on  the  terminal.
!       Indicate the end of a TAKE file with a little message.  Abort all takes
!       when we a ^C is seen and we are yet the spooler doing a take.
!       Gregory A. Scott 23-May-86
!
!  202  Fix /AFTER:TODAY again (groan),  daylight  savings  time  wasn't  being
!       handled properly.
!       Gregory A. Scott 23-May-86
!
!  200  Don't  allow  non-disk  output  files  for  DIRECTORY if the command is
!       queued.  Also check that input and output files are on disk (if local).
!       Add (yet) more hair to PARERR to eat  the spaces at the end of a  field
!       before trying to eat the field itself.
!       Gregory A. Scott 22-May-86
!
!  174  The help command tables were broken sometime in the past.
!       Gregory A. Scott 20-May-86
!
!  172  Change prompt to DIUDEB if debugging.  Really remove LIBRARY 'TOPS20'.
!       Gregory A. Scott 20-May-86
!
!  171  Add routine C$CONTROL_C to  handle  the  control-c  interrupts.   If  a
!       control-c is seen in a TAKE and we are yet the spooler,  then  we  just
!       set the current take JFN to eof.   Remove call to S$TRACE, just do  the
!       $DEBUG call here instead.  Use MONSYM and JSYSDEF rather than TOPS20.
!       Gregory A. Scott 19-May-86
!
!  167  Add hair to SW_ARGUMENT to the area that prevents double colon typeout:
!       this fixes a rather obscure case of a switch completed with escape that
!       takes an argument and  the user types a  question mark and that  switch
!       happens to end at a  place where there is a  colon left in the  command
!       buffer from a previous command (check that the next unparsed  character
!       is a  colon  and  the last  parsed  character  is not  a  colon).   Use
!       S$NODE_CHECK for all  nodes parsed and  turn on the  parse only bit  in
!       CMNOD, since we want to be smart about nodes that are offline.
!       Gregory A. Scott 19-May-86
!
!  165  Turn off the interrupt  system while running in  DIU$DO in the  request
!       routine.  This to to prevent getting bombed out to the exec because  an
!       active slave job  or some user  sent us  an IPCF message  while we  are
!       running in RMS  with a section  3 stack.  Yes,  it is gross  but so  is
!       doing non-queued requests from the spooler job.    Edit 163  broke  CCL
!       takes, which is fixed now.  Have macro PE append a CRLF to his strings.
!       Gregory A. Scott 16-May-86
!
!  164  Rename D$SHDF to SHODEF and don't pass it  an  unused  third  argument.
!       Avoid using crufty $MSG_FAO macro.
!       Gregory A. Scott 16-May-86
!
!  163  Clean up DIUCMD to get the take file JFN installed in the command state
!       block differently and remove routine D$$COMAND which apparently  was  a
!       debugging aid.
!       Gregory A. Scott 15-May-86
!
!  161  Make the  /LSA switch  erase properly  on a  parse error  (like  /IMAGE
!       already specified in the command line) by always calling sw_argument at
!       the start of the rfm_switch  routine then retstoring the command  state
!       with rststa at the end of that same routine if it was the lsa switch.
!       Gregory A. Scott 14-May-86
!
!  156  Remove /USAGE (the usage  is set in the  description file) and  /NONRMS
!       (the file's FDB is checked for the RMS file class) switches.  Make  the
!       record format switches illegal with /IMAGE file format.
!       Gregory A. Scott 13-May-86
!
!  154  The /IMAGE switch should add a tag of diu$k_fab_fac  with  a  value  of
!       fab$m_bio for DIUDO's use.  Use -1 generation on the output  side  of a
!       remote filespec.
!       Gregory A. Scott 12-May-86
!
!  152  Have spooler job write the "request queued" message to user log file.
!       Gregory A. Scott 11-May-86
!
!  151  Fix PARERR to backup the command buffer over the last switch, so that a
!       ^H after some PARERR  generated error looks  proper and correct  (yuk).
!       Don't allow /TRANSFORM or /DESCRIPTION with /IMAGE file format.
!       Gregory A. Scott 9-May-86
!
!  150  Give a  parse error  on  the following:  /RMS:INDEXED without  /KEY  on
!       destination  side,   /TRANSFORM   without  source   /DESCRIPTION,   and
!       destination  /DESCRIPTION  without   source  /DESCRIPTION  means   that
!       destination must be /RMS:INDEXED.
!       Gregory A. Scott 9-May-86
!
!  147  Log the creation of a request in the user's log file.
!       Gregory A. Scott 8-May-86
!
!  146  Print a message if we can't queue the request (checking status returned
!       from IP_ENTER in the REQUEST routine).
!       Gregory A. Scott 7-May-86
!
!  144  DIU$MESSAGE calls from here now never write to the system LOG file.
!       Gregory A. Scott 7-May-86
!
!  143  REQUEST routine didn't ever use OWN variable txtbuf and LOCAL  variable
!       ptr.  The defaulting of the request switches (/LOG and /NOTIFY) is  now
!       done by  rewritten DEF$REQUEST  which calls  DEF$BUFFER and  so  forth.
!       Don't default the notify and log file stuff in INIT_REQUEST dince it is
!       done in  DEF$REQUEST now.   Remove notify_value  (no longer  used)  and
!       mvalue (write only variable).  The /SPAN_BLOCKS switch should result in
!       a tag value of NOT FAB$M_BLK, and /NOSPAM should result in FAB$M_BLK.
!       Gregory A. Scott 6-May-86
!
!  142  Rename LOG routine to  ST_LOG,  remove  routine  ST_NOLOG,  moving  its
!       rather limited function to ST_LOG.  Fix /NOLOG_FILE switch.  DEF$BUFFER
!       now returns the length of the field it just set up.
!       Gregory A. Scott 5-May-86
!
!  141  Work  on  /KEY  so  that  it  only  allows  one  [NO]CHANGES  and   one
!       [NO]DUPLICATES per  key.  Fix  up  help strings  for the  /KEY  switch.
!       Uppercase the job name in MKJOBNAME.
!       Gregory A. Scott 5-May-86
!
!  140  ST_DEFAULTS was broken  if setting def_root  entries.  The /LOG  switch
!       doesn't default  the  connected  directory  right  since  the  JFNS  to
!       retrieve all  of  the  parsed  file  specification  isn't  returning  a
!       directory since the JFN is done generically parse only for an old file.
!       So, save the default directory in DEF$INIT for us to plug in as needed.
!       Rename SET_MJOB_ACTION to  ST_MJOB and teach  it to see  if we are  the
!       spooler or there is not (yet) a spooler before allowing MJOB to be set.
!       Gregory A. Scott 3-May-86
!
!  137  Only check  node validity  once in  DSTNOD and  SRCNOD, by  looking  at
!       context  VALID_NODE.   Rename  ST_ACCESS   to  ST_UPA  (user   password
!       account), and clever it up  to take VMS-style embedded access  strings.
!       Remove SRCACC and  DSTACC, calling ST_UPA  instead.  If input  filename
!       was a quoted string, the default  the output filename and type to  *.*.
!       Rename SET_DEFAULTS_ACTION, to ST_DEFAULTS, clever  it up a little  bit
!       to make it set both types of  SET DEFAULT command, then we can get  rid
!       of SET_NODE.  Work  on LOG  file routines included  defaulting the  log
!       file spec inside of INIT_REQUEST and simplification of routines LOG and
!       NOLOG.  DEF$CREATE should be maintaining the linked list,  rather  than
!       having each caller do it.
!       Gregory A. Scott 3-May-86
!
!  136  Make keys work for indexed files.
!       Sandy Clemens 1-May-86
!
!  135  Make the SET MAX command output the current setting of MJOB if we  are
!       (yet) the spooler.
!       Gregory A. Scott 1-May-86
!
!  134  SET MAX error message needed a space in the error message that you  get
!       when you specify an out of range number.  SHOW MAX now says "There  are
!       n requests executing"  if there  are slave jobs  running.  Remove  cell
!       stopped since cell shutdown is what should be used.
!       Gregory A. Scott 30-Apr-86
!
!  133  Change messsage in EXIT_COMMAND if you are (yet) the spooler to have  a
!       CRLF after  it (in  case called  by ^C  trap).  Remove  MACY11 code  in
!       FILFMT_SWITCH.  /IMAGE should only be global.  Output better message in
!       SRCNOD when we parse junk due to CMFLD (adding messages missing  source
!       file specification, bad switch, properly indicate file not found).
!       Gregory A. Scott 29-Apr-86
!
!  132  Routine PARERR turned on the noparse bit but it also cleared the CM_XIF
!       bit, causing "@" not to be handled locally after a noparse.  Add  entry
!       point for exit_command routine to call upon a ^C.
!       Gregory A. Scott 28-Apr-86
!
!  130  Routine MAKEPROMPT  should  be global  so  that  it can  be  called  by
!       SP$START and SP$SHUT.   (Yet) again  default the  filename properly  in
!       SRCFIL and DSTFIL if the file was remote and not quoted.
!       Gregory A. Scott 28-Apr-86
!
!  127  Rework /PREREQ and /SEQ logic: Change /PREREQ switch to allow NONE  for
!       modify and don't allow a request id of less than 2.  Remove NO and  YES
!       options   to    /SEQUENCE   switch.     Remove   sequence_switch    and
!       last_sequence_switch and previous_id cells, add pre_id cell.  Implement
!       switch conflicts for /SEQUENCE with /QUEUE:NO.
!       Gregory A. Scott 26-Apr-86
!
!  126  SHOW VERSION, MAX, and TAKE don't look right in TAKE files because they
!       don't output a CRLF at the end of the string, since MSG_FAO doesn't  do
!       it anymore.   INIT_REQUEST  didn't  specify its  formal  arguments.   A
!       command of the form "STOP/NOW/WAIT/NOW/WAIT" used to work; now it  only
!       lets you type one switch.
!       Gregory A. Scott 26-Apr-86
!
!  125  Minor change due to deletion of the "free" crlf furnished by  $MSG_FAO.
!       /VFC:(n:m)  was  broken  because  it  called  RSTSTA  after  the  first
!       argument; now ST_BYTE and  ST_HALFWORD check cstate and  do not do  the
!       RSTSTA if  we are  in a  state inside  the /VFC:(n:m)  switch.   SRCFIL
!       should always  default  the  file  name and  type  even  if  they  were
!       wildcarded.
!       Gregory A. Scott 4-Apr-86
!
!  123  Parse of CMQST should be before CMFIL when parsing after the  nodename.
!       Remove the  extra states  for the  DELETE command  (we use  the  common
!       remote input states instead now).  Default generation should be "*" for
!       the DELETE command.
!       Gregory A. Scott 23-Apr-86
!
!  122  Routine request didn't get  new lengths of  the source and  destination
!       filespec after  calling DEF$BUFFER,  resulting in  very short  filespec
!       lengths when access information was applied.
!       Gregory A. Scott 22-Apr-86
!
!  121  Fix up  help  for  filespecs  after nodenames.   Remove  last  call  to
!       S$JFN_STR, and remove  external routine  of Q$CONFIRM,  which is  never
!       called.
!       Gregory A. Scott 19-Apr-86
!
!  120  Additional work to  make parsing  of source  and destination  filespecs
!       work better, or at least differently.  Allow "::" after node  specified
!       in SHOW DEFAULTS.   GETFILESPECS is now  PRE_INPUT.  SRCNOD and  DSTNOD
!       were carelessly changing  the $GJGEN  flags that are  patiently set  up
!       elsewhere.  Default  the directory  list level  properly in  PRE_INPUT.
!       The ill-conceived routine SPECIAL_CASES doesn't do anything useful  but
!       default the filename and list level for the DIRECTORY command (which is
!       now done where it should be), so delete it.  Change flag_node_set  cell
!       to rflags[R_NODE].  Cells def_queuevalue, def_notify, and  def_sequence
!       were really constants, so replace them by the constant.
!       Gregory A. Scott 18-Apr-86
!
!  117  Routine REQUEST  doesn't  need to  be  global; and  it's  not  anymore.
!       Default the output filename properly on the directory command by giving
!       a default string on the first flddb in the chain after the filename  is
!       parsed.  Implement checking  for conflict between  /AFTER /DEAD  /QUEUE
!       switches.  Implement  switch conflicts  for /DESCRIPTION.   Check  that
!       /DESCRIPTION and /TRANSFORM files are on disk.  Allow SHOW DEFAULTS  to
!       take a nodename.  Routine MANIPULATE_ACTION did too much work that  was
!       done in INIT_REQUEST, and its name conflicted with another routine that
!       really did useful work.  Now  the routine is called PRE_MANIPULATE  and
!       does very little.  TAKE_SET_DEFAULT  is now PRE_TAKE.  /AFTER:+5  broke
!       somewhere in the last few edits.
!       Gregory A. Scott 17-Apr-86.
!
!  116  Add proper switch conflict errors for /[NO]SPAN_BLOCKS.  Fix parsing of
!       multiple  word   switches   (e.g.   /FILE_FORMAT:FIXED:n)   by   having
!       SW_ARGUMENT eat  colons  off of  the  CMKEYed second  word.   Make  the
!       default second word to /FILE_FORMAT: be RMS:.  Rework command  scanning
!       of filespecs so that quoted filespecs work rationally.  Remove  $PARSEs
!       in DSTFIL and SRCFIL since they didn't provide anything useful:  quoted
!       string filespecs didn't  parse if you  were typing a  [P,PN] and if  it
!       wasn't a quoted string the GTJFN  done by COMND checked the syntax  and
!       JFNS can be  used to  extract the name  and type  for defaulting.   (In
!       other words, if  the user id  doing a quoted  filespec assume he  knows
!       what he is  doing and  let the remote  FAL parse  the filespec  later.)
!       Invent two  cells (src_node  and dst_node)  that store  the source  and
!       destination node  names  for MKJOBNAME's  use,  making its  job  a  lot
!       easier.  Remove following  storage which was  never used or  is now  no
!       longer used: sesa, desa,  srsa, drsa, snam,  dnam, sfab, dfab,  filcnt,
!       trace.  Teach GETFILESPECS about the  DIRECTORY command so that we  can
!       remove  routine  DIRECTORY.   Remove  brain  damaged  GETADD   routine,
!       replacing it  with calls  to newly  clevered up  GETFILESPECS.   Remove
!       routine ESAFNA which is no longer used.
!       Gregory A. Scott 14-Apr-86
!
!  115  Implement checking of multiple  /USERID, /PASSWORD, /ACCOUNT,  /ACCESS,
!       and fix bare  /ACCESS switch.  Give  better help on  all four of  those
!       switches.  Remove  cells set_all_aci,  set_acct, set_pass,  set_userid,
!       since they have now been replaced  by rflags bits.  Remove MACY11  file
!       format,  /[NO]BLOCKING_FACTOR  switch,   and  routines   ST_BLK_FACTOR,
!       FAC_SWITCH, and FAC_NSWITCH.  Put break mask on /RECORD_FORMAT switch.
!       Gregory A. Scott 9-Apr-86
!
!  114  Implement checking  of  multiple  /[NO]AFTER,  /[NO]DEADLINE,  /NOTIFY,
!       /PRIORITY, /[NO]LOG_FILE, /[NO]QUEUE, /PREREQUISITE, /SEQUENCE switches
!       in same  command.  Remove  cells  set_notify, set_queue,  and  set_log.
!       Make default ext for /LOG_FILE be LOG.  Change routines ST_LOG and  LOG
!       to use rflags bit and context.  Remove very strange code in SW_ARGUMENT
!       and FILE_ARGUMENT  that attempted  to "hallucinate  the default  string
!       into the atom buffer" if no terminating colon was seen on a switch;  it
!       made parsing  of  switches  unlike any  other  TOPS-20  program.   Move
!       clearing of key_count and stopswitches to INIT_REQUEST.  Remove routine
!       STOP_SETUP as it only cleared stopswitches.
!       Gregory A. Scott 8-Apr-86
!
!  113  Change usage of COMMAND_EXIT and EXIT to EXIT_STATE, and usage of  SAME
!       to SAME_STATE.   Replace calls  to  INIT_COMAND with  INIT_REQUEST  and
!       delete   INIT_COMAND.    Change   references   of   seen_requestid   to
!       rflags[R_REQUESTID].  Remove  /[NO]DEFERRED  switch, since  it  doesn't
!       make sense to have it as a synonym for /QUEUE.  Remove ability to  type
!       /SEQUENCE:nn, since that functionality  exists in the  /PREREQUISITE:nn
!       switch and having it both places is misleading.  Add routine PARERR  to
!       print parsing  errors; new  macro  PE calls  PARERR and  then  RETURNs.
!       Change  all  SIGNALed  errors  for  parsing  into  PE  calls.    Remove
!       FOP_NSWITCH and RAT_NSWITCH and install call FOP_SWITCH or  RAT_NSWITCH
!       with inverted context.  Repair totally  broken /VFC switch.  Add a  lot
!       of switch conflict logic to many switches (/USAGE illegal with /LSA  or
!       /STREAM or /CARRIAGE_CONTROL; detect multiple /TRANSFORM and /WARNINGS;
!       allow /KEY only  on output file  that is /RMS:INDEXED;  only allow  one
!       /USAGE, record  format,  file format,  /CARRIAGE_CONTROL,  /CONTIGUOUS,
!       /NEW|/OLD per filespec).
!       Gregory A. Scott 7-Apr-86
!
!  112  Change the abbreivation for the EXIT  command (EX) so that it uses  the
!       CM_ABR bit  and RELATED=  option, which  is the  right way  to have  an
!       abbreviation in the command table.  Implement /AFTER:[TODAY|dayofweek].
!       Clean up /AFTER parsing in general.
!       Gregory A. Scott 3-Apr-86
!
!  114  Change sflags and dflags to be a BITVECTOR of 36.  Remove  /QUEUE:MAYBE
!       (superceded by /QUEUE:CONDITIONAL).   Change switch  tables around  for
!       COPY and  APPEND  so  that  there  are  five  seperate  switch  tables,
!       differing by the context in  which they are parsed: request  (anytime),
!       input (after  a input  file only),  output (after  a COPY  output  file
!       only), append (after APPEND output  file only), and global (before  any
!       filespecs typed  only).   Add  CM_SDH  to CMIFI  and  CMQST  in  DELETE
!       command.  Make invisible command of EX so that you don't have to  spell
!       out "EXI" to  exit.  For SUBMIT,  default file type  to .CTL and  allow
!       wildcarded filenames  in  GETFILESPECS.   GETFILESPECS  shouldn't  call
!       INIT_REQUEST either.  Default generation properly for DELETE and RENAME
!       to *.
!       Gregory A. Scott 2-Apr-86
!
!  106  Remove output of  extra blank line  when a job  is queued.  Remove  the
!       following switches: /BLOCK,  /NOBLOCK, /NOCARRIAGE_CONTROL,  /UNDEFINED
!       on COPY and APPEND; /OUTPUT on DIRECTORY.  Routine MKJOBNAME put spaces
!       after the job name it made up, causing job names less than 6 characters
!       not to match  in Q$MATCH  (e.g.  SHOW  QUEUE jobname  wouldn't work  on
!       DIRECTORY and DELETE  commands), so  I rewrote it  using CH$  functions
!       rather than  $STR  functions to  make  it work  simpler,  smaller,  and
!       probably faster.   Default directory  filename to  nodename.DIR  rather
!       than DIR.DIR; removes some CMCFMs to make that work right.  A new  fork
!       was created by each PUSH command but old forks were never killed;  make
!       PUSH continue any old EXEC it  has sitting around.  TAKE, EXECUTE,  and
!       "@" now default extension to CMD.  Prompt now changes to "DIU spooler>"
!       if we are the spooler; routine MAKEPROMPT resets the prompt now.
!       Gregory A. Scott  1-Apr-86
!
!  102  Conform SHOW  VERSION to  look like  SHOW QUEUE  and DEFAULTS.   Change
!       hyphens to underscores in  MAXIMUM_SIMULTANEOUS_REQUESTS.  In order  to
!       make SET  DEFAULTS  work somewhat  more  rationally, it  has  has  been
!       changed to SET  DEFAULT {node::|SWITCHES}  [/switch/switch].  This  was
!       done for clairity and because SW_ARGUMENT  was doing bad things to  us.
!       Repair GET_REQUEST_ID,  SHQ_GET_REQUEST_ID,  and  MODIFY_GET_REQUEST_ID
!       parsing: change  help string  "Request  identifier" to  "Request  queue
!       entry, decimal  number"; add  better help  when parsing  <username>  or
!       [username] when specifying a request already in the queue; only  accept
!       the right  flavor of  delimiter  for usernames  (e.g.  match  "<"  with
!       closing ">"), which actually simplified parsing the field; remove extra
!       CMCFMs which  allowed  illegal  commands  to be  parsed  and  add  flag
!       seen_requestid do do the  job the right  way.  Split FILFMT_TABLE  into
!       two tables:  INP_FMT_TABLE  (legal  on input  files  and  OUT_FMT_TABLE
!       (legal on output files).
!       Gregory A. Scott 28-Mar-86
!
!  100  Use "!V" to  print version rather  than splitting it  up ourselves  for
!       printout in  SHOW VERSION.   Make nested  TAKE commands  work right  in
!       terms of echoing or not echoing.  Add SET TAKE to set the default  take
!       echo mode and  SHOW TAKE to  display the default  take mode.  Make  CCL
!       TAKE (even nested!) work again.  A  CCL command that didn't parse  left
!       you in DIU, which is fixed by setting cmdnpt to COMMAND_EXIT to  return
!       control to DIUCMD.
!       Gregory A. Scott 26-Mar-86
!
! 77    Move clearing of  def_node to  INIT_REQUEST where  it belongs.   Remove
!       somewhat strange CCL  command logic  and replace  with simple  ccl_mode
!       flag.  Each command now has a NEXT state of COMMAND_EXIT, which  causes
!       each command to  terminate in routine  DIUCMD.  DO_MORE and  associated
!       logic has been removed.  TAKE tried to  do a RLJFN of a open JFN  which
!       doesn't work (it now does a CLOSF).  Make TAKE and "@" illegal from CCL
!       commands (for now).
!       Gregory A. Scott 25-Mar-86
!
! 76    Fix reparsing  of  command lines  by  setting CMDRPR  (command  reparse
!       routine) to  INIT_COMAND.   This  fixes ^W  and  ^H  problems.   Remove
!       unimplementable switch FIMAGE.  Pass  0 as third  argument to EPCAP  to
!       prevent WARNing about AC3.  Add DATA=10 to /BLK_FACTOR:n switch so that
!       "n" can be  parsed.  Add help  strings to CMKEY  and CMSWI parsing  for
!       better help on  "?".  Revise  some noise  words to  confirm to  TOPS-20
!       EXEC.  Add CM_SDH to CMNOD to prevent seeing both "source filespec" and
!       "node name" (since source filespec implies node name).
!       Gregory A. Scott  24-Mar-86
!
! 75    Fix /KEY: switch to support key option flags CHANGES, NOCHANGES,
!       DUPLICATES and NODUPLICATES and to support the correct syntax!
!       Change /KEY: action routine so that the key command text is saved
!       in a buffer in the REQBLK and parsed later.
!       Sandy Clemens   19-Mar-86
!
! 73    Make all /WARNINGS and /USAGE information be stored in the REQBLK
!       structure (not in global flags -- this won't work for queued
!       requests).
!       Sandy Clemens   4-Mar-86
!
! 72    Define WARNINGS_COUNT and if /WARNINGS:n was not specified by the
!       user, then set WARNINGS_COUNT to the default which is 1.  Remove
!       WARNING_MAX.
!       Sandy Clemens   3-Mar-86
!
! 70    Add setting F_RAT, F_RFM, F_NONRMS bits in SFLAGS and DFLAGS when RAT,
!       RFM or NONRMS seen.  Add CONTEXTs to /RMS:INDEXED, /RMS:SEQUENTIAL,
!       /RMS:RELATIVE.  Remove "need_usage" (not used anymore).
!       Sandy Clemens  25-Feb-86
!
! 65    Change command switches: 1) remove /DATATYPE, add /USAGE 2) remove
!       /ORGANIZATION, add /FILE_FORMAT.  Change NAM$V_PWD bit to NAM$V_SYNCHK
!       bit in SRCFIL and DSTFIL routines.
!       Sandy Clemens  12-Feb-86
!
! 64    Add GLOBAL patpar_warn which is a flag that gets set if the
!       DIU$_PATPAR informational condition is seen, and which is
!       cleared when either DIU$_PARDES error condition or DIU$_PARTRA
!       error condition is seen.
!       Sandy Clemens  15-Jan-86
!
!  61   Remove $CMOFI (output file function) from APPEND_GET_INPUT,
!       COPY_GET_INPUT, DELETE_GET_FILESPEC, PRINT_GET_INPUT,
!       SUBMIT_GET_INPUT and RENAME_GET_INPUT command table states.
!       These were work-arounds for a COMND bug which has now been fixed,
!       and they now cause DIU problems.  FILE:  DIUC20.B36.
!       Sandy Clemens   16-Dec-85
!
!  60   Implement /OUTPUT: switch for DIRECTORY.
!       Sandy Clemens   16-Dec-85
!
!  56   Fix routine FILE_ARGUMENT so /TRANSFORM and /DESCRIPTION switches
!       work.  Reorder the action routines alphabetically.  Implement TAKE
!       switches (/ECHO, /VERIFY, /NOECHO, /NOVERIFY).  Remove the "transfer"
!       switches from PRINT and SUBMIT commands.  Add /WAIT to STOP command.
!       Sandy Clemens   3-Dec-85
!
!  52   Fix bug in $STR_SCANs in DECIDE_QUEUE routine.  When setting up
!       for prompting, make sure the PROMPT_CHARACTER is ASCIZ!
!       Sandy Clemens   12-Nov-85
!
!  46   Make the queue decision smarter.  Remove /NOTIFY:FAILURE code.
!       Clean up SET DEFAULTS code.  JOBNAME was being set to trash for
!       a local to local request -- set it to "LOCAL" instead!
!       Sandy Clemens   4-Nov-85
!
!  44   Add missing SET DEFAULTS switches /DEFERRED and /NODEFERRED.
!       Sandy Clemens   17-Oct-85
!
!  43   Make routine REQUEST make a more intelligent decision about
!       whether to queue a requeust.  Make numerous switches which
!       were the old FTS format be the new DIU format.
!       Make /CARRIAGE_CONTROL work.  Fix the /TRANSFORM switch which
!       was being processed by /DESCRIPTION states...  Add CRLF after
!       "request queued" message.
!       Sandy Clemens  11-Oct-85
!          
! V01-042  Sandy Clemens  11-Oct-85
!          Make 'mjob' and 'mst_flag' EXTERNAL rather than OWN variables.
!
! V01-041  Sandy Clemens  10-Oct-85
!          Implement PUSH, SPAWN and EXECUTE commands in DIUC20.B36.
!
! V01-031  Sandy Clemens  17-Sep-85
!          Change name of DIU-COMMAND.R36 to DIUCOMMAND.R36 to make
!          porting to TOPS-10 easier.  (TOPS-10 will truncate DIUCOMMAND
!          to DIUCOM, but cannot bypass the "-").
!
! V01-027  Andy Nourse 22-Aug-85
!          Fix absent rename output file, make take prompt after finishing.
!
! V01-024  Andy Nourse 18-July-85
!          Put in /DESCRIPTION, /TRANSFORM, /KEY and /WARNING_COUNT
!
! V01-002  RDF0002            Rick Fricchione              17-Jan-1985
!          Fix ridiculous first attempt at filespec storage logic and
!          tag buffers.  Make global tags get stored prior to filespecs
!          and make sure $ETG and $NUL are in correct locations.
!
!
! V01-001  RDF0001            Rick Fricchione              17-Dec-1984
!          Original version. Convert from FTSCMD, rewrite to create 
!          request blocks for back end which resemble VAX DIU blocks.
!          Have parser dump tag values into request file buffers, and
!          store filespecs in formatted manner.

ROUTINE add_tag (tag, tag_type, p_value, val_len, p_buffer) : NOVALUE =
BEGIN
!++
! FUNCTIONAL DESCRIPTION:
!
!       This routine is responsible for appending file attribute information
!       to the tag buffers in module static storage.  These tag buffers are
!       maintained seperate from the filespec, and when the completed filespec
!       is detected, appended to it.
!
!       The format of the filespec in the request block is as below.
!
!     +-----+
!     | len |  request[DIU$H_SOURCE_FILESPEC]
!     +-----+-----+-------+-----+-----+----------+-----+-----+-------+-----+
!     | tag | tln | value | etg | fln | filespec | tag | tln | value | nul |
!     +-----+-----+-------+-----+-----+----------+-----+-----+-------+-----+
!        ^                   ^     ^         ^      ^           ^
!        +--------+----------+     +----+----+      +-----+-----+

!          global qualifiers      file occurrence   local qualifier
!
!     Global qualifiers default to all filespecs in the list, although the
!     actual tag information is recorded just once.  The propogation of this
!     information is done when the actual FABs are being built.
!
!        len      - the overall length of the request block filespec buffer
!        fln      - the length of just the upcoming filespec in the buffer
!        tag      - byte literal indicating field in FAB/RAB/XAB to be set
!        tln      - length of tag value
!        value    - the actual tag data 
!        etg      - end of tag byte ($ETG)
!        nul      - a null byte which ends filespec to keep it ASCIZ 
!
!
!        The stream ALWAYS ends on a nul byte, and that nul byte is always 
!        found on the starting address + .len bytes.
!
!        * WARNING *  To be compatable with the way VAX DIU handles tag values,
!                     integer values are converted to ASCII and trimmed of any
!                     leading zeros.  At run time these values are converted
!                     back to binary.  This allows us to treate all tag values
!                     as character data similar to VAX DIU.
!
! FORMAL PARAMETERS:
!
!        tag         Literal found in DIU.R36 which indicates field in 
!                    FAB/RAB/XAB to be set.  (passed by value)
!
!        tag_type    Literal indicating value type (DATE, INTEGER, STRING)
!                    Needed to duplicate value in buffer. (passed by value)
!  
!        p_value     Used depending on tag type above.  If a string, interpret
!                    as a CH$PTR to the text.  If an integer, then interpret it
!                    as the address of a BLISSword value. 
!
!        val_len     Value length.  This indicates the length in characters of
!                    the value we will deposit.  (passed by value)
!
!        p_buffer    Tag buffer we will operate upon.  This is a CH$PTR to 
!                    the request block fields usually. (passed by REFERENCE)

!       for RMS indexed  files and are  only allowed for  the destination  file
!       (since the source files XABKEYs will contain all of the KEY information
!       once $OPEN is  called for  the source file).   The /KEY  switch is  not
!       allowed for ISAM files since DIU doesn't create ISAM files (except in a
!       block mode transfer where the data format is irrelevant).
!
!       NOTE: It would take lots of  space to create and store data  structures
!       with all the key names and information (especially a problem for queued
!       requests).  Also, it is impossible at the time of command line  parsing
!       to validate that the field names specify actually exist in the  record;
!       however, this can  be checked  after the record  description trees  are
!       built.  Therefore, instead  of expanding the  command line  information
!       during command parsing, the  information typed in by  the user will  be
!       saved and expanded later.
