;Base level set 22JUN81
;
; EDIT HISTORY - to change edit # search for occurance of "!!!"
;
; Edit # Date Description
;
; 1 26JUN81 Change INCLUDE KDP command to allow multipoint
; control/tributary for inhouse use only.
; Also, CHANGE command fixed so it doesn't try to
; change the phys addr of a multipt trib if "outhouse"
; Also, don't allow INCLUDE/EXCLUDE MULTIDROP on kdp
; command if "outhouse"
; Also, fix it so that the version and edit info really
; comes out in the prog header and the output files'
; .ident info.
; Also, delete the code sections in the FINISH
; command that produce the DEV$DFs, CTL$DFs, and the
; UNT$DFs for the line printer and the card reader.
; They now have PRC$DFs and LLC$DFs.
; Also, change the definition of RDB.sz in NETPAR to be
; <DL.blk+6+1>&<-2>
; 2 15JUL81 FINISH command fixes
; Fix $TEXT macro string for writing std RSX-Task
; header to avoid writing a blank line in CETAB if
; the standard task POSI is not to be included
; (ie, if node is a DN20)
; At same place, always include DTR as a std rsx-task
; whether or not there are any non-std ones, and
; regardless of node type. This is to prevent RSX11S
; from crashing when Session Control asks for a task.
; Also, fix it so there are no blank lines between the
; CTL$DF sections for DTE, DMRs, DMCs
; 3 07AUG81 Add vector, csr and priority definitions for line
; printer and card reader to NETPAR
; Also fixed TSK$DF DTR in CETAB so it is never a comment
; line
; 4 10AUG81 Put in LOG command - log and take commands check out
;
; 5 31AUG81 Changes to handling of variables FLOWCT & NRLNUM:
; Add line "ND.fld = 3 ;NRD - Low Water Flow Count" to
; NETPAR
; Delete or comment out all refs to variable FLOWCT
; and routine FLOCLC
; Make default #NRM pipes = 1
; Fix bug in formula that resets #NRM pipes in routines
; incl/excl cr/lp, node type from
; if NRLNUM.ne.0 add 1
; to
; if NRLNUM=0 add 1
; The two variables in NETPAR, NR.flw and ND.flw, were
; being set to the value of FLOWCT - they are
; seperate, with values of 4 and 10 respectively
; Make CHANGE FLOWCOUNT command inhouse only - it should
; not be reset by the user
; Add user commands to change NETPAR parameters:
; Inactivity Timer NTPACT (NS.act)
; Delay Factor NTPDLY (NS.dly)
; Rexmit Threshold NTPRET (NS.ret)
; Round Trip Delay Est NTPWGT (NS.wgt)
; 6 03SEP81 Additional changes to output files:
; CETAB:
; Standard Process LIB taken out
; For DN200s, add standard RSX driver TT
; Always include TSK$DF for NML
; NETPAR:
; literal XP.ibq set to 8 if dn20
; 20. if dn200
; add line 'macro' 39.,<POSI..>
; to SC$obj macro, if dn200
; 7. 08SEP81 Take out Delay Factor command after all
;
; 8. 09SEP81 CETAB changes recommended by Lee Webber:
; Take out PRC$DF and LLC$DF for DTR - it has a TSK$DF
; NOTE - TAKE OUT TSK$DF DTR FOR FIELD TEST!!
; Take out PRC$DF KMC - no such process
; Include PRC$DF and LLC$DF for NRM/NRD only if
; node type = dn200
; AND
; #nrm pipes (NRLNUM) > 0
;
; 9. 17SEP81 Add range checks to following commands:
; CHANGE Inactivity Timer (range 0 - 30)
; Retransmission Threshold (1 - 15)
; Round Trip Delay Est. (1 - 255)
;
; 10. 21SEP81 Rename the CHANGE ROUND TRIP DELAY command to be
; CHANGE DELAY WEIGHT, its real name in NSP.
;
; 11. 02OCT81 Change the PDB for 'node name' command from $CTEXT
; to $FIELD - ctext allows special characters and
; embedded spaces, which are illegal for node name
; Also add code to GETNOD to reject node names with
; any chars not in {0-9,a-z,A-Z}
;
; 12. 02OCT81 Change all "_" to "-" in link specs. Affects:
; -parsing commands (chg phys addr KDP, excl kdp,
; incl multipt drop, incl kdp)
; -retrieving parsed args
; -STNXDR, rtn to put multipt drop #s into prompts
; -information command (links, KDPs)

;
; 14. 12OCT81 Change def of CCBLEN in FINMOD from 28. to 34.

; Text and decimal parsing reversed from DSNODE in $TEXT
;
; macro.
; 9. 24Jan83 Add object type 31. for Gateway module in SC$PRO and

; used I2 instead of I1 to access object number. (LDX in
; FINMOD.
; 24. 07Apr83 Don't list module MCB-Executive unless privileged.
; 25. 08Apr83 Do not include the DCP process in CETAB if there are

; maintain these counters.
; 26. 19Apr83 Excluding a KDP device must set the default protocol
; type (LNTYPE).
; 27. 09Sep83 Including a LAPB KDP followed by including a DMR
; line fails. The code for specifying DUPLEX (DL1111:)
; is executed for DMx devices but it checks LNTYP which
; is defined only for KDPs. Remove the check.
; 28. 19Jan84 Fix CALL MASK and VALUE for X25 to produce the correct
; octal bytes.
; 29. 13Jul84 Fix the code to produce the macro TSK$DF XNM in

; 33. 18Oct84 Fix code in NETCNF.MAC to keep the default
; configuration file name null if there is no node name
; for building the file name with.
;
; 34. 26Nov84 Remove PHASE-II keyword for DEFINE EXECUTOR RECEIVE/
; TRANSMIT PASSWORD commands. Turn on these commands
; for the field as well as the DEFINE LOGGING FILE EVENT
;
; 35. 06Jan85 Updated all copyright notices. Include a patch that
; fixed multiple definitions of label ENTNO1 in module
; NETPRM that was causing incorrect code to be generated
; by MACRO. Include a rewrite of routine CHKNAM to
; disallow node names not beginning with an alphabetic
; character.
;
; 36. 07Jan85 Remove all visible references to DN200's in TOPS20
; NETGEN by removing parse table entries for
; INCLUDE/EXCLUDE card-reader/lpt and INFORMATION
; card-reader/lpt/node-type; set PDN200 to zero.
;
; 37. 17Jan85 Insert Transmit Password query into START dialog
;
; 38. 15Jul85 Merge NETGEN & X25GEN
;
; 39. 25Jul85 Continue merge of NETGEN & X25GEN by:
; Fixing INCLUDE KDP test for X25 nodes; removing
; node type question in START dialog; prompting for
; the node type at program startup; removing the set
; node type command; replacing the information node
; type command.
;
; 40. 4Sep85 More work on merging NETGEN & X25GEN: use switches
; to select between NETGEN, X25GEN, and both. Turn
; on FT.NET for NETGEN, FT.X25 for X25GEN, and turning
; on both will produce the merged version. Default for
; TOPS-20 is NETGEN and both for TOPS-10. Also beef up
; error handling after prompting for node type at program
; startup.

SUBTTL Command processing routine (COMMAND)
Comment &
This is the top level command processing routine. It does the call
to the syntactic PARSER and then vectors to the appropriate service routine
depending on the value of the first keyword in the command string.
&
COMMAND:
MOVX S1,PAR.SZ ; Size of the parser arg block
SKIPN S2,STEMP ; Address of parser argument block
MOVEI S2,PARBLK
$CALL PARSER ; Parse a command
JUMPT CMMD.1 ; Success in parsing a command
MOVE T1,PRT.FL(S2) ; Get PARSER flags
TXNE T1,P.ENDT ; End of TAKE file?
JRST [SETZM TAKFLG ; Clear TAKE file processing flag

$CALL DSPCMD ; Optionally display the command
MOVE T1,PRT.CF(S2) ; Get COMND flags
TXNE T1,CM%ESC ; Escape last character?
$TEXT ,<> ; Yes .. move to new line
$TEXT ,<?^T/@PRT.EM(S2)/> ; Output error message
JRST COMMAND ; Go get a good command
CMMD.1: MOVE S1,PRT.CM(S2) ; Get address of command page
MOVEM S1,PPAGE ; Save page address for releasing
MOVE T1,PRT.FL(S2) ; Get flags from PARSER
$CALL LOGGIT

TXNN T1,P.TAKE ; TAKE command?
TXNE T1,P.NPRO ; No processing for command?
JRST CMMD.4 ; Already done in ACTION routine
MOVE S2,COM.PB(S1) ; Get offset to parser blocks
ADD S1,S2 ; Make address to start of blocks
$CALL P$SETUP ; Start semantic parsing
SKIPN S1,STEMP ; Get parser block
MOVEI S1,PARBLK

$CALL @PAR.SM(S1) ; Call semantic routine.
JUMPF CMMD.4 ; Try again if failure.
SETZM STEMP ; otherwise finished with sub-command.
SKIPN S1,SCMND ; If in sub-command sequence
MOVEI S1,PARSEM ; then
SETZM SCMND ; cancel current routine
$CALL (S1) ; before calling it.
CMMD.4: MOVE S1,PPAGE ; Get page address of command
