TOPS20 Change Order Number 4.1876

Problem:
EDIT COMPLAINS ABOUT AN OUTPUT FILE ALREADY EXISTING WHEN IT
REALLY ISN'T THERE. AN EXAMPLE IS IF THE USER HAD DEFINED
HLP: AS DSK:,HLP:. THE COMMAND EDIT HLP:SORT.HLP SORT.HLP
WOULD THEN COMPLAIN WHEN IT REALLY SHOULDN'T.
Diagnosis:
WHEN CHECKING TO SEE IF THE OUTPUT FILE ALREADY EXISTS, THE
MONITOR IS TOLD TO SEARCH THROUGH ALL LOGICAL NAMES, NOT
ONLY THE FIRST ONE.
Solution:
SET THE GJ%NS BIT IN THE GTJFN AT END2+2, SO THAT THE MONITOR
WILL ONLY LOOK FOR THE FILE IN THE FIRST DEFINITION

Problem:
IF COMMANDS ARE BEING READ FROM A FILE, AND WE DO AUTO-SAVES,
THEN EDIT BLOWS UP WITH THE ERROR "JFN NOT ASSIGNED" WHEN THE
AUTO-SAVE IS COMPLETED.
Diagnosis:
A RESET IS DONE AS PART OF THE SAVE THE WORLD ROUTINE, WHICH
WIPES OUT THE INDIRECT FILE'S JFN.
Solution:
AT ENDEND+7, DELETE THE GENERAL CLOSF AND CALL A SUBROUTINE CLSALL
WHICH WILL EITHER DO THE GENERAL CLOSF, OR IF THE INDIRECT FILE
IS BEING USED, SEPARATE CLOSFS FOR ALL OTHER FILES. ALSO REMOVE
THE RESET AT RESTRT.

Problem:
PROTECTIONS OF FILES GET CHANGED BY EDITING THEM. IF NO OLD
DELETED GENERATION OF A FILE EXISTED, THE NEW FILES ALWAYS GOT
STANDARD PROTECTION. IF A DELETED FILE DID EXIST, THE NEW FILE
GOT THE OLD FILE'S PROTECTION.
Diagnosis:
EDIT MAKES NO ATTEMPT TO KEEP THE PROTECTIONS NICE.
Solution:
REMEMBER THE PROTECTION OF THE ORIGINAL FILE, AND SET THE NEW FILE'S
PROTECTION TO IT ALSO. ALSO SET THE .Q?? FILE'S PROTECTION TO THE
SAME VALUE. THIS INVOLVES CODE AT END1B+4, END4+10, AND IN TSTNEW.

Problem:
TRYING TO RUN A PROGRAM WHOSE FILE SPEC WAS AN EXACT MULTIPLE OF 5
CHARACTERS FAILED.
Diagnosis:
THE PRARG TO WRITE THE SPEC FOR THE EXEC DIDN'T MAKE SURE A NULL BYTE
ENDED THE SPEC, THUS THE EXEC GOT CONFUSED WHEN READING IT.
Solution:
ADVANCE THE BYTE POINTER PAST THE NULL BYTE, SO THAT IT IS ALWAYS
WRITTEN AS PART OF THE PRARG BLOCK. AT CRFIT1-2, INSERT IBP T1.

Problem:
/RUN FEATURE LOSES BIG. IT DOES NOT WORK AT ALL, AND WHEN IT IS GIVEN
A BAD FILE SPEC, EDIT GETS AN ILLEGAL INSTRUCTION.
Diagnosis:
CODE DOESN'T KNOW DIFFERENCE BETWEEN TTY INPUT, STRING INPUT, OR
FILE INPUT (FOR THE CASES OF TERMINAL COMMAND, RESCANNED MONITOR COMMAND,
AND OPTION FILES).
Solution:
FIX UP SETRUN AND RUNME CODE TO HANDLE ALL THESE CASES.

Problem:
On a copy command, if the lines get out of order, the message output is
ORD1=ORDER, which is not too informative. It should be the standard
error message for this case.
Diagnosis:
Code is a kludge.
Solution:
If we get an order error, set a flag to remember it, and when the copy
is all done, if the flag is set then give the out of order message.
Also output nothing for ORD1= if out of order.

Problem:
Disk full interrupts are not handled properly.
Diagnosis:
The DSKTRP code assumes that the PC returned on a trap pointes to the
next instruction, but in fact it points to the offending instruction
itself. Thus its "CAI" check never succeeds.
Solution:
Look at the right instruction.

Problem: CREATE command using a temporary file spec doesn't preserve
the temporary atribute. Thus CREATE FOO.BAR;T create a file with
a high generation number, but is not temporary.
Diagnosis:
The bit goes away. However, creating a temporary file should be
illegal, since generation numbers mean things to a temporary file, and
we should not be randomly bumping the generation number. This will
happen on AUTO-SAVE actions.
Solution:
Give an error if the user is trying to create a temporary file.

Problem:
If no tabs is specified for a terminal, and a file is edited, the
first line of a "P" command has a space missing between the line
number and the first character of the line. Similarly, when a <LF>
command is given, the line is missing the character.
Diagnosis:
On display terminals, EDIT tries to be fancy and overprint the asterisk
typed on the command line. It does this by sending the cursor up sequence
to the terminal. The monitor takes the characters sent as motion
characters, and so on the next tab simulates fewer spaces.
Solution:
Output carriage returns after the cursor up sequences, so the monitor
will reset its line position to the front of the line.

Related SPR's: 12612
Problem:
A CONTROL-C WHEN ANSWERING THE QUESTION "DO YOU WANT TO SUPERCEDE FILE"
FOLLOWED BY A QUIT COMMAND BLOWS EDIT UP WITH ILLEGAL DEVICE DESIGNATOR
ERROR.
Diagnosis:
THE QUIT CODE CALLS THE DELOUT ROUTINE. BUT AT THIS POINT IN TIME,
NO JFN EXISTS FOR THE OUTPUT FILE. THUS OCRJFN CONTAINS 0, AND THE
CLOSF FAILS.
Solution:
AT DELOUT, RETURN IF NO OUTPUT JFN EXISTS.

Problem:
After an illegal insert command, such as "IX", the "P^" command
gives the error "no such lines" instead of typing the first line.
Diagnosis:
Flag UPTOPF gets set by the insert command, and is usually cleared
afterwards. But on an insert error, it gets left on.
Solution:
Clear the flag on errors also. In the routine CKIND, also clear UPTOPF.

Problem: THE TRANSFER COMMAND CAUSES AN ILLEGAL INSTRUCTION TRAP
ON AN "% ILLEGAL TRANSFER DESTINATION" ERROR.
Diagnosis: THE COPY CODE SETS THE ISCOP FLAG IN THE FL FLAG WORD
TO INDICATE THAT LOCATION "COPDL" HAS THE STACK POINTER TO USE ON
ERROR RECOVERY. "ISCOP IS SET IN 2 PLACES IN EDIT, COPY2+4 AND
OTHERF+112, BUT COPDL IS ONLY ASSIGNED A VALUE IN TE SECOND INSTANCE.
IN-CORE TRANSFER ERRORS BLOW UP, SINCE THE CODE NEVER REACHES OTHERF,
AND COPDL CONTAINS A 0. THUS, THE STACK POINTER IS RESET TO 0.
Solution: WHEREVER ISCOP IS SET, BE SURE COPDL HAS A VALID STACK
POINTER.

Problem:
If device HLP: is defined as PS:<HELP.*>, or any reasonable string that includes
a wildcard, the EDIT 'H' command will fail to find HLP:EDIT.HLP.
Diagnosis:
When EDIT gets a JFN on HLP:EDIT.HLP, it does not use the GJ%IFG bit to allow
for wildcards in the filespec, so in this case the GTJFN fails.
Solution:
Set the GJ%IFG bit at location HELP+3, before the GTJFN, and then clear the
returned flag bits in the JFN word before saving it on the stack at location
HELP+7 : HRRZ T1,T1.

Problem: WHEN A "P" COMMAND WITH NO ARGUMENTS IS FOLLOWED BY ANOTHER
"P" COMMAND, ALSO WITH NO ARGUMENTS, THEN THE LAST LINE OF THE FIRST
"P" COMMAND IS PRINTED TWICE.
Diagnosis: "P" COMMAND DOES NOT RECALL THAT THE LAST LINE PRINTED
WAS THE CURRENT LINE.
Solution: ADD A VARIABLE "PNOARG" SO THAT IN THE OUTLIN RTN
IT IS SET TO -1, AND IN THE PRNT5 RTN SET "PNOARG: TO A +1.
