Problem: 
EXAMINE and DEPOSIT commands need to be more useful.

Diagnosis: 

Solution: Make EXAMINE and DEPOSIT default addresses.
Defaulting will be done as follows:
  - There will be no initial default
  - EXAMINE will default to the last address EXAMINEd plus one
    if the last operation was EXAMINE
  - EXAMINE will default to the last address DEPOSITed
    if the last operation was DEPOSIT
  - DEPOSIT will default to the last address DEPOSITed plus one
    if the last operation was DEPOSIT
  - DEPOSIT will default to the last address EXAMINEd
    if the last operation was EXAMINE

Thus, alternate EXAMINEs and DEPOSITs will always reference the same
address; while successive EXAMINEs or DEPOSITs will reference successive
locations.

Problem: TAKE files don't echo.

Diagnosis: Feature not implemented.

Solution: Add feature.
New subcommand to the TAKE command:

	@TAKE,
	@@ECHO (COMMANDS FROM "TAKE" FILE)
	@@
	@

This subcommand causes all commands processed during a TAKE file
to be typed on the user's console terminal (or TAKE log file).
Each complete command is typed as it is processed, preceeded
by the prompt that would have been typed for the command.

Note that this mode stays enabled for all TAKE files until
it is disabled:

	@TAKE,
	@@NO ECHO (COMMANDS FROM "TAKE" FILE)
	@@
	@

Note that TAKE with no arguments but with subcommands only
affects the state of the subcommands.

TAKE with no arguments or subcommands terminates the current command
file level, as always.

Problem: 
DOCUMENTATION SAYS THAT TMOUNT GIVES:
	?OPERATOR NOT IN ATTENDANCE (OR SOME SUCH MESSAGE)
IF THE OPERATOR IS NOT IN ATTENDANCE.  IN ACTUALITY, TMOUNT
IGNORES THE OPERATOR-IN-ATTENDANCE FLAG.

Diagnosis: 
NO CODE TO CHECK THE OPERATOR-IN-ATTENDANCE FLAG.

Solution: 
ADD CODE TO CHECK THE FLAG.  IN ADDITION, CHANGE MESSAGE TO A WARNING:
	%OPERATOR NOT IN ATTENDANCE	(SAME AS SMOUNT'S WARNING)
THEN, GO AHEAD WITH THE TMOUNT REQUEST.  CHANGE THE MESSAGE FOR TMOUNT
FROM [OPERATOR NOTIFIED] TO [WAITING FOR TAPE TO BE MOUNTED].

Problem: IN EXEC, TYPING "SYS D.SCHEIFLER" PRODUCES WRONG
RESULT.  IT SHOULD SHOW INFO ABOUT USER D.SCHEIFLER, BUT DOESN'T.

Diagnosis: EXEC SEES "D" AS KEYWORD "DIRECTORY", "." AS MEANING
SELF, AND "SCHEIFLER" AS ANOTHER ARG.

Solution: CHECK TERMINATOR OF KEYWORD, IN THIS CASE "DIRECTORY".
IF IT'S ".", REINTERPRET INPUT WITHOUT KEYWORD AS A POSSIBILITY.
THIS WILL CAUSE "D.SCHEIFLER" TO BE SEEN AS A USER NAME.

NOTE THAT THE EXEC ALREADY DOES THIS TYPE OF TRICKERY FOR THE CASE
OF:

	@SYS:MACRO

THE EXEC FIRST SEES THE "SYS" AS SYSTAT, AND THEN SAYS, "OH, IT'S
TERMINATED WITH ":" SO MUST NOT REALLY BE SYSTAT, BUT MUST BE THE
BEGINNING OF A FILESPEC!"

Problem: if you define snark: as foo: and then say delete foo.*,
exec prints strange error message

Diagnosis: Although the GTJFN on FOO.* succeeds, the JFNS reveals SNARK:
as the device, which RCDIR then can't find because FOO: doesn't exist.
(we were connected to real SNARK:!).  Exec was calling an error routine
which assumed AC1 contained an error code.  In this case, however, RCDIR
didn't fail, it merely had a no-match.

Solution: Print real error message if RCDIR fails
This type of problem probably happens all over the place.  That is, define
a logical name that's the same as your connected structure, such that the
definition points to a nonx structure.  Then reference a file on DSK: such
that exec or other prog ends up trying to take the jfn, do a JFNS, and then
tries to feed the structure string to another jsys.

Problem: In the exec, the SET PAGE-ACCESS command is too verbose about
reporting failures.  Also, its failures were coming out as warnings instead
of real errors.

Diagnosis: I didn't feel like making the code smart before.  Tonight I'm
ambitious.

Solution: Be clever and print only one error per block of consecutive pages
that fail for same reason instead of error per page.  Also, print as real
error instead of warning.  This was previously a warning merely because there
didn't used to be an internal mechanism in the exec to print an error and return
to the caller.  Now there is so we can print real errors without bombing
out the command before all requested pages have been processed.

Problem: If user specifies more than one file in a TYPE command, the exec
is supposed to name each file as it types it out.  The command
"TYPE A,B" fails to announce each file however.

Diagnosis: this worked in r2, and seems to have been broken in r3 and since.
The CFN1 routine in the exec was changed dramatically in r3, and the bug
was introduced there.

Solution: Light the flag saying a file group has been input (GROUPF), whenever
a subsequent filespec is guaranteed (such as user typing a comma after previous
filespec, in a situation where subcommands are impossible).

Problem: 
When an EXEC is built without symbols, the last page is sometimes
missing in the .EXE file.

Diagnosis: 
EXEC expects the last required address to be XEND.  However, LINK
loads in SYS:MACREL.REL after this address, and PAT.. is placed
after this.  If this additional code and storage crosses a page
boundary, it will not be saved.

Solution: 
Make EXEC use one less than the contents of .JOBSY as the last
required address.  That location points to the first symbol in
the symbol table.

Problem: If you are doing alot of fancy things with exec such as "FORK n"
commands, the exec gets confused and a "DDT" command can cause

	?Illegal instruction 0,,0 at 770000


Diagnosis: Exec has cell DDTFLG which it sets when DDT gets loaded, such that
subsequent DDT command can be efficient instead of figuring out whether to
load DDT again.  After FORK command, exec gets fooled by DDTFLG into thinking
that DDt is already loaded for other fork!

Solution: clear DDTFLG whenever FORK command is given

Problem: On heavily loaded system, when exec starts on new job, it can type

and then go into an infinite loop of typing an error message

Diagnosis: this TCO only covers one problem.  That is, at ERRFIN, there are
some PUSH'S and POP's, and the POP's win by one!!!!!  Since the exec doesn't
reset P after an error, this cause a flushdown plunderflow.

Solution: Remove the PUSH's and POP's completely.  (Noone was expecting the
ac's to be preserved there anyway)

Problem: ON "INFO DIR", EXEC CAN SAY "DIRECTORY GROUP BUFFER OVERFLOW" WHEN
NOT SO.

Diagnosis: EXEC WAS CHECKING TO SEE IF LAST WORD IN BUFFER WAS 0 AFTER GTDIR,
WHICH IS INVALID, SINCE THE WORD ISN'T INITIALLY 0 BEFORE THE GTDIR.
(THIS PROBLEM DIDN'T EXIST WHEN THE GROUP BUFFER WAS IN GLOBAL INSTEAD OF
LOCAL STORAGE IN EARLIER RELEASES, IN WHICH ALL STORAGE IS ZEROED ON EVERY
COMMAND)

Solution: CHANGE THE CHECK TO BE TO SEE IF THE COUNT OF GROUPS RETURNED BY
GTDIR IS MAXIMUM, IN WHICH CASE PRINT THE OVERFLOW MESSAGE.
NOTE THAT GTDIR IS DEFICIENT, AS IT HAS NO WAY OF TELLING THE CALLER THAT
THE ALLOTTED GROUP SPACE ISN'T LARGE ENOUGH FOR ALL GROUPS.  HENCE FOR
DIRECTORIES WITH EXACTLY THE MAGIC NUMBER OF GROUPS, THE EXEC FALSELY SAYS
"GROUP OVERFLOW"

Problem: If you have a COMAND.CMD that sets up some defaults for you, and you
run an exec for the purpose of patching it, and put the patched one up on
SYSTEM:, everyone gets your defaults!  That is, you patch it like this:

	@RUN SYSTEM:EXEC
	@ENA
	$^EDDT
	patch patch patch patch...
	CINITF/	-1	0
	^Z
	@SAVE SYSTEM:EXEC

Diagnosis: exec wasn't clearing defaults upon startup

Solution: Move the default database to the section of memory that the exec
clears upon first startup.  This way, whenever the exec is started with CINITF
set to 0, it will clear all defaults.  Hence it's O.K. to save a patched exec.

Problem: In exec, if you use BUILD or ^ECREATE, and try the KILL subcommand,
and don't confirm properly, you're supposed to be back at subcommand
level.  Observation shows that you cannot succeed in typing any more subcommands
at this point.

Diagnosis: Exec wasn't properly saving P away at beginning of subcommands, to
be restored after an error during a subcommand.  The problem only
shows up if a subcommand causes a prompt, as with [CONFIRM] under KILL.

Solution: Recreate cell called .P which P gets stored in at beginning of
subcommands, and which error handler copies to P after an error if it's
non-zero.

Problem: In exec SUBMIT command, one can't say /TIME:25:0:0, for instance.

Diagnosis: Exec uses monitor's dat-and-time JSYS's (via COMND) to read
the time.  These JSYS's restrict input to 24 hours, because they assume
a time of day is being read, rather than an amount of time.

Solution: Make exec not use that method.  Instead, exec will call
GETAMT, a local routine it already uses for reading amounts of time
in other places (like /AFTER:TODAY+45:0:0)

Problem: "LOAD @FOO" typed to exec causes "?Not confirmed".

Diagnosis: This recently broke when a COMND fix caused COMND to no

on CM%XIF for LOAD-class commands, but not for their guidewords!

Solution: In exec, before parsing "(FROM)" as in "LOAD (FROM)", turn
on CM%XIF.  (Exec was already turning on CM%XIF for parsing the
rest of the command)

2)	Certain errors such as "PRINT /YECCH" print two error messages,

Solution: Make CERR do a CMERRX.  Fix $CMERR to print single line
error message.

What this heiroglyph means for documentation:

1)	Any manuals which document that the exec prints a lone "?"
	should be changed to say the exec prints an appropriate error
	diagnostic.

2)	The double-line error messages in which both lines started with
	"?" now print a single error message line.

Problem: INFO MEM takes too long

Diagnosis: Three factors:

1)	The RPACS JSYS in the monitor is now slower due to extended

	pages total so that total can be printed before map.

3)	In the map printer routine, the exec seems to do RMAP and RPACS
	per existent page.  Only RMAP is needed.

Solution: 1)	Buffer the output in a string so that the same JSYS that
	gets the page info can be used to count how many pages.

2)	Do only RMAP per page, not RPACS.

Problem: In exec, if user tries to say null password by just typing
carriage return in response to

	PASSWORD:

he just gets reprompted.  Instead, exec would like to assume null password
in that case.

Diagnosis: COMND merely reprompts by default if user types return at
beginning of line.

Solution: Do .CMCFM at beginning of line, which COMND regards as a special
case.  IF .CMCFM suckseeds, assume use is giving null password.

Problem: 
If you type "RENAME FOO.FOO <DBELL>" and file FOO.FOO doesn't exist, EXEC
gives ?FILE NAME NOT SPECIFIED

Diagnosis: 
If FOO.FOO doesn't exist then MFOUT uses no default filename to parse
the output filespec.  "<DBELL>" does not contain a filename, hence the
error message.  The message doesn't occur if you have more than one
input filespec, because then MFOUT defaults the file and extension to
*.*

Solution: 
If there is only one input filespec, and an error of the file not found
variety occurred, allow MFOUT to finish the parse by defaulting *.*
for filename and extension.

Diagnosis: The ^EEDDT command write-enables the exec.  Hence the bug

Solution: Change ^EEDDT to not write-enable the exec.  The write-enabling
used to be necessary in order to allow breakpoints to be put in.  However,

Problem: If you ^C out of DIRECT [*]*.FOO for instance, a partially
created jfn lies around.

Diagnosis: I removed CLZFF from ^C loop to speed it up.  Usually the
CLZFF isn't needed, since the exec stacks every jfn with JFNSTK, and
^C loop unwinds the stack.  However, there are a few places, like
wildcard searching, that if user types ^C between GTJFN (in COMND!) and
the JFNSTK call, jfn can lie around.

Solution: Use new flag called CLZF to signal that CLZFF better be done if
^C.  Set this flag before calling COMND (since @MUMBLE may be typed), and
clear CLZF after COMND comes back, if function successfully parsed was
not a filespec function.  Clear the flag in JFNSTK too, after stacking the
jfn.

Problem: Exec sometimes leaves jfn's around

Diagnosis: JFNSTK tries to remember what to close, but UNMAP wipes out the
info.  Also, DIRFL / DI3 replaces tape jfn with another after rewinding, hence
the jfn stack doesn't remember all the jfn's that need closing.

Solution: Use GTBUFX / XBUFFS instead of GETBUF / BUFFF for stacking erroneous
jfn at CFNE1.  That way, UNMAP won't hurt the jfn stack.  Also, at DIRFL / DI3,
be more careful about leaving even the old jfn's stacked.

Problem: COMPIL-class commands fail with comments in them, such as

	@COMP FOO !This comment should be ignored!

Diagnosis: The exec parses the COMPIL-class commands twice, once with COMND
	and once again with TEXTI and the exec's own special parsing routines.
	COMND handles the comments fine.  The exec trips on them.

Solution: In the CMPRES routine which already removes extraneous spaces, remove
comments too!

Problem: The command COMP FOO.MAC with a trailing space causes a compilation
even though the .REL is current.  This is particularly annoying with
situations such as

	@COMP FOO.MAC !comment

which has a trailing space when the comment is stripped during parsing.


Diagnosis: None attempted.  However, a preprocessor already removes spaces
in other places in the line for similar reasons.

Solution: Fix the preprocessor (CMPRES) to remove trailing spaces.

Problem: Switches appearing after commas in COMPILE-class and PRINT-class
commands do not apply to the files which follow a la TOPS-10.  These file
specific switches must appear either globally (before ANY file specs) or
locally (after any particular file spec), but not in a semi-global context,
i. e., after a comma.

Diagnosis: Code tends to ignore commas, and apply any switches to the most
immediately preceding file (if any).  This is clearly counterintuitive, and
misleading at best.  It is most difficult, however, to force the switches
to apply to only the following file specs.  Therefore, we are forced to make
all file-specific switches forbidden after a comma is seen, and allow them
only at the beginning of commands (global), or after a specific file (local).

Solution: As in the diagnosis.  Observe that this also makes it illegal to
confirm a command of the above form after a comma is seen - one needs to
give a file spec after any comma seen before allowed to confirm.  This
only seems right!

Problem: Defining LPT: as DSK: causes INFO STR * to list connected structure

Diagnosis: Exec loops through names in DEVNAM table via GETAB and

and exec prints it.

Solution: Try a STDEV and see if same string comes out as went in.  If not,
assume it's DSK or logical name and skip it.  Hence LPT will go in and come
out as PS (or some other structure) which won't match, so LPT will get
correctly skipped!  Clever, isn't it?

Problem: If an illegal instruction is executed in location 777777,
the EXEC gets an error within an error. The particular case that
caused this was 777777$G typed to DDT.

Diagnosis: The routine that prints the PC of the illegal instruction
attempts to decrement the PC by one (since the hardware has
incremented it before the trap), but does so with full-word
instructions. This is contrary to the hardware, which increments
PCs MOD the size of a section. The EXEC thus ends up with an
address of 777777,,777777, or -1. This address is then passed
to LOADF and then to MAPPF, which treats a -1 as a command
to unmap the currently mapped page, and things lead down hill
from there.

Solution: Decrement the PC by 1 without a carry from the
left half of the address.

Problem: 
If take files are nested too deeply, the EXEC will not type out the
message "TAKE commands nested too deeply", but will instead say
"?Pushdown overflow internal trap".

Diagnosis: 
In the routine PUSHIO, the EXEC stacks information about the current
command level.  The PUSH instruction has an ERJMP after it which is
not taken.

Solution: 
It would be nice to fix the monitor to make ERJMP after a PUSH which
gets an overflow work.  But this is nontrivial.  So for now just have
the EXEC avoid the problem by checking for overflows by hand.

Solution: Remove all references to the flag entirely.  It isn't really needed,
since it signals an error condition that the exec never allows to occur, namely
that of there being no free slot into which to recieve an IPCF message.  Since
the exec makes a free slot either by processing some of the messages received
already, or flushes a message (and prints a warning) the situation will never
happen.

Enhance CMPRES routine to strip carriage returns and change linefeeds to
commas.  Instead of reading indirect file characters directly from file
while parsing, read the entire file into a buffer and then call CMPRES so
that the comments get correctly interpreted.  (Note that CMPRES was already

Problem: TV can bomb out with

	?JFN is not assigned

Diagnosis: Exec does its general jfn flushing after all commands including
ones that do GET jsyses.  Since the monitor has already closed the jfn used
by the GET jsys, another program may now be using it (TV in this case!) so
when the exec flushes it, TV loses whatever file it was using on that jfn.

Solution: The exec should not try to close the jfn used by GETs.  This is
effected by throwing the jfn off the jfn stack in the exec after the
GET jsys.

doesn't have formfeeds.

Solution: Make TERM FORM and TERM INDIC be independent.

Problem: On exec operations, file data errors don't print a very informative
message.

Diagnosis: The exec only prints the PC, not a very useful piece of information.

Solution: There are many device-dependent status situations that can
conceivably be reported.  However, for now, we'll respond to SPR # 20-13102
and merely do what they asked:

	1)	The message will no longer include the PC.

	2)	The filespec will be printed that caused the error.

	3)	If it's a magtape and it has reached end of tape, the
		exec will tell the user that.

Problem: Sometimes, a magtape command given to the exec will take a real long
time because the operator has to mount another volume.  The user can't ^C
out while this is happening.

Diagnosis: The exec was disabling ^C while it did its GTJFN on the tape, so
that it was assured of being able to stack the jfn before ^C happens, in order
to know to flush the jfn later.

Solution: Use CLZFFF instead of PIOFF in order to know to do CLZFF if ^C happens
in sticky spots.

Problem: When using COPY or APPEND with long files, the message "%Unexpected
error: page table does not exist and file not open for write
proceeding..." sometimes appears.

Diagnosis: 1) a file with a section long hole in it and
2) a file whose EOF pointer points to the last page of a section

during some copy operations (eg disk-nondisk) and APPENDS, EXEC attempts
to optimize it's time by prefaulting pages from the file. if the set of pages
it wants to preload are in a non existent section, the preload operation
fails but causing no problems for the continuation of the COPY/APPEND.

Solution: before preloading pages--
1)check for non-zero section
2)see if pages have already been preloaded from this section
3)check to see that the section needed really exists

NOTE: long files with section long holes in them will be doing an extra FFUFP
JSYS for EVERY PAGE in that section.

Problem: Lower forks can get a JFN that an EXEC above it is using for a TAKE
command and mess around with (EG close it). Upon returning to the upper level
EXEC, if the JFN for the command file or the log file is cloased, EXEC throws
up. This is particularly bad when the EXEC itself is put in a lower fork (as
in a PUSH command within a TAKE file). The CLOSE command in particular will
simply close the JFNs the upper EXEC is using.

Diagnosis: A lower EXEC, in executing a CLOSE command, simply loops around
looking for valid JFNs. It finds the JFNs for the upper EXEC's TAKE command
and closes them, unaware of the special status of these JFNs.

Solution: Whenever JFNs are obtained for the TAKE command, make them restricted
to the current fork or higher by turning on the GJ%ACC in the COMND call.

Problem: /logname: switch to SUBMIT command hadles the log file differently
from the way default log file is handled. Currently will always overwrite it.

Diagnosis: If the /logname: switch is not used, EXEC passes BATCON a filespec
built from the connected structure/directory the CTL filename and .LOG for the
extension. No generation number is passed. When the /logname: switch is used,
the filespec parsed will be passed to BATCON, including the generation number.
Since EXEC is parsing a filespec with the GJ%FOU bit on, BATCON will always
be getting a filespec on a new file instead of the original.

Solution: 1) Don't pass the generation number to BATCON.
2) Have EXEC parse the log filespec so that it will recognize an existing
file or allow creation of a new one. (No GJ%FOU bit in GTJFN call)

Problem: HELP * DOESN'T HANDLE THE KEYWORD LISTING AS INTELLIGENTLY AS HELP ?

Diagnosis: EXEC IS TRYING TO SIMULATE WHAT THE COMND JSYS DOES ON A QUESTION
MARK BUT DOESN'T CHECK THE LENGTH OF EACH KEYWORD IN THE KEYWORD TABLE BEFORE
TRYING TO PRINT THEM. THIS CAUSES THE COLUMNS TO NOT LINE UP CORRECTLY.

Solution: GET RID OF THE PARSING OF THE STAR (*) SINCE IT DOES ALMOST THE SAME
THING AS THE QUESTION MARK (?).

Problem: The FIND subcommand feature of DIRECTORY-class commands is broken.

Diagnosis: The particular algorithm the exec uses to do FIND depends on
the filespecs being buffered.  A recent "improvement" in the DIRECTORY
command involves printing specs immediately instead of buffering.  This
breaks FIND.

Solution: For now, merely add FIND as the list of options requiring buffering,
along with CHRONOLOGICAL.  A future improvement might be to change the FIND
algorithm so as not to require buffering.

Problem: The TDIRECTORY command gets screwed up if the directory is so large

results.

Diagnosis: There is a longstanding bug that causes the sort routine to
sort one more word than is in the table.  This bug didn't used to show up
if we ran out of fdb buffer space before the sort table got used up.  However,
now that the sort table exhausts first, we see the bug.

Solution: Check for length sorted table, instead of looking for a 0 beyond
the end of the table.

Problem: 

	@DEFINE DBELL: DSK:
	@SYSTAT DBELL:

	fails!

Diagnosis: DBELL matches user name, and then colon causes confusion.

Solution: COMND has a general problem that if the first few characters of the
input matches some field in the chain fed by the program, and gobbling more
characters matches a field further down the chain, the first field matched
is opted for.

Fix COMND to see which field in the chain matches most input and use that
one.  So DBELL: is a better match for directory than user name, since the colon
can be included for directory name.  Hence make COMND match DBELL: with .CMDIR,
regardless of where .CMDIR is in the chain with respect to .CMUSR.

The old way was bad because in order to get recognition of user names, you
have to put .CMUSR before .CMDIR, since "DBE<esc>" will be ambiguous as a
directory name, but recognizable as "DBELL" as a user name.  On the other hand
we'd like to put .CMDIR first so that "DBELL:" gets interpreted as a directory
name.

The new way gets it all right!

Problem: If you start up a fresh exec and say

	the help message correctly lacks carriage return as an option,

Diagnosis: The check for whether to allow carriage return was not made at

Solution: Make the check in COMIN.  Note that the entire TI routine doesn't
	always get it right.  It assume that indirect files have filespecs
