How many Line a DCL can manage on VMS 5.5

Bui_2 — Fri, 24 Sep 2004 04:54:56 GMT

Hello

I want to kwnow, how many line a DCL in VMS 5.5 can manage

because when a DCL exceed 10 000 lines, the GOSUB command respond -W- the label not found.

and my boss want a proof

where i can find this information

thx all

Just created a script of 47500 lines.
No problem on 7.3 and 6.2.

No 5.5 over here.

But did you check the script with dcl_check (freeware cd) ? Most of the time there is a quoting problem when your error is given.

thx for your quik answer

the error is typpicaly error when you foget the label of your GOSUB command

%DCL-W-IVVERB, unrecognized command verb - check validity and spelling

but the label is here, the first version of script (9200 lines) works well, but when i add other command in the middle of my script (10 027 lines)
the gosub command don't work whereas when i run the first version of my script it run good

and i don't have your freeware i'm just an analyse, i answere the system cell for this thanks

scuse the error is

%DCL-W-USGOSUB, target of GOSUB not found - check spelling and presence of label

Could you post the script ? And the working script too ? Then I can check it.

ok how?

I'vw just created a DCL procedure like:

$ ws "Hi 1"
$ gosub test
$ ws "Hi 2"
$ exit
$ sh time
...some 12000 more lines
$!
$ test:
$ ws "test"
$ return

and ran it under V5.5-2 without problems, so it is not a problem mit 5.5-2.

BUI,

well, there IS a limit, but that is NOT the number of lines of DCL, but the total space in P1 space. That is where (a.o.) your DCL symbols, and your DCL label info, are maintained. And if you have A LOT of symbols and or label, and/or many string symbols with long string valies, THEN P1 space can get exhausted.
My V5.5 experience IS a bit rusty, but IMMSMW, then 5.5 already knew the SYSGEN parameter CTLPAGES. Nowadays it is dynamic, but those details and the 5.5 limits you will have to find yourself.

If on YOUR system you do
$ MC SYSGEN HELP SYS_PARAMS CTLPAGES
that will give the details for YOUR system
(not sure, but maybe SYS_PARAMS was called PARAMS then, but certainly MC SYSGEN HELP
will show you the exact syntax.

The limits for CTLPAGES used to be not really big, but we HAVE had success with it.

Try, and tell us your results.

If this does not help, or does not help enough, you may also get results if you explicitly remove symbols if (maybe temporarily) no longer needed
( $ DELETE/SYMBOL , for global symbols also add/GLOBAL

I seem to remember that there was a restriction like that in the past. I don't remember the exact details. I think it had something to do with the number of labels between the calling point and the subroutine, not the number of lines. (I may be wrong here)

Is the routine in question in the beginning of your code or at the end?

If you move the code of the subroutine, does that eliminate the error?

You can post the script by transferring it to the PC and then use the "browse" button in the reply screen to select the file.

I had a similar problem this morning but with GOTO instead of GOSUB. I had entered an IF-THEN-ELSE structure between the GOTO and the destination label but I forget to enter the ENDIF. Once I entered this keyword the procedure worked correctly.

thank for your answer

it seem the good way

my boss will be happy

:)

this is the procedure, if you can give me more details or information

i want learn the secret's of vms lol

this problem interressed me

The command SHOW PROCESS/MEMORY will display the statistics about dynamically allocated area in the process control region P1.
This may help to determine if you have an issue with insufficent available space in this area.

Wim Van den Wyngaert — Fri, 24 Sep 2004 07:48:13 GMT

So, was your problem solved ?

In any case, I ran dcl_check and found :
LINE CODE --DIAGNOSTIC MESSAGE--
676 WCT wrong constant type for comparison
814 INT IF statement not terminated
1339 DL duplicate label "CDENLIVR_MX"
4041 LNF label "RCPTDELOC" not found
4069 LNF label "RCPTDELOC" not found
4099 LNF label "RCPTDELOC" not found
4527 RLI referenced label "EXT_INVE_GB" is in if-group at lines 4539-4630
9869 CRE code cannot be reached due to EXIT at line 9868

Bui_2 — Fri, 24 Sep 2004 07:53:41 GMT

no my problem is not resolve i search

thanks for the error msg. but i don't understand why the first GOSUB doesn't work with all the answer in this thread i think the procedure have too many label or symbol

can you test the procedure you may change the firs GOSUB TSTLOGICAL on GOTO TSTLOGICAL and insert en EXIT after the label TSTLOGICAL. if the script work at your home...i definitely don't understand :(

DCL went on tilt because of syntax errors.

You should
1) correct all the errors found by dcl_check
2) make sure that the if's are in balance. Check the if's on line 842 and following. I find dubious things around line 862.
3) indent if then else and endif on the same position to find the inbalances.

Bui_2 — Fri, 24 Sep 2004 08:22:09 GMT

then why if i delete any random 800 lines in the middle of script and i run with the change GOSUB command with the exit the first GOSUB work well

Re: How many Line a DCL can manage on VMS 5.5

labadie_1 — Fri, 24 Sep 2004 09:17:02 GMT

While this does not answer you problem, I am surprised that you are not in Vms 5.5-2 or 5.5-2 H4, which are supported versions.

And for me, a Dcl procedure should not exceed 20 or 30 lines, so I have never met a similar problem :-)
When it exceeds, I write it in another langage (you have a lot of choice with Vms, C, Pascal, Ada, Python, Perl, Fortran, Cobol...)

Best of luck.

Labadie,

The only thing a system manager must know is DCL. So I write in DCL and my monitoring is now 4000 lines of DCL. But dcl_check conform.

I I wrote a program in lets say ALGOL, nobody would correct the errors when I'm gone.
