Can any tell me how to call a cobol program from an easytrieve.

How to compile the cobol program?

How to specify the load module in the program?

If possible can anyone cut and paste the required parts of the modules.
thanks,
ricky

Hello,

Calling a cobol module from easytrieve is very similar to calling a cobol program from another cobol program.

All you need is this
Code:
CALL COBPGM USING ('a literal', AFLD)
in the easytrieve code. This example shows passing both a literal and a data field to the called module.

You can also specify RETURNS to recieve the return code from the called module.

Hi Dick,

How we have to specify the load module?

Hello,

In my example COBPGM is the name of the cobol load module.

Compiling the called module is the same as compiling it for being called by another cobol program. You might create a simple cobol program to call your module and then call it via easytrieve making sure both perform the same way.

Hello,

You should not need to link it with the eztrieve code.

Try the test i mentioned earlier using a dynamic call in the test cobol calling program (rather than a static call). I do not believe there should be any linkedit issues.

If i can, i'll try something later tonight or tomorrow.

In the meantime, i'd suggest you give it a try and if anything unexpected happens, post back here and we'll figure it out.

Hello,

Have you had success yet?

Sorry that i've not gotten back sooner, but when i tried to put this on a system, a few surprises happened.

I'm trying to determine if there are release level issues/differences. Which release of Easytrieve are you using?

I've also moved the topic to CA Products from the COBOL part of the forum so maybe others who are currently doing this will post how this works on their system.

FYI, Make sure the steplib has the location of the compiled cobol load module

Hi All,
I tried whatever mentioned here and my program is giving a return code of 0. But my easytrieve module is not calling the cobol module.Could any one having the sample code past it here?

Thanks,
Ricky

Try adding this to the first statment in program

PARM DEBUG (STATE) ENVIRONMENT(COBOL) LIST (FILE PARM)

Did you get to the called programs? Post up your code.

Here is a quick sample:

CALL PENDACCS USING (IO-CONTROL-AREA +
PEND-IO-RECORD +
PEND-IO-REAL-KEY +
AK-RECORD)

Are you using Ent. Cobol? Did you add the SCEE lib to your steplib?
Where did the Soc4 occur....Cobol program or EZt? Post the line number and error messages.

Please try to provide as much detail as possible so that we can help.

Hello,

Sorry for the delay. Turns out the system w/ ezt is running a very old ezt (6.3) and some of the code i used would not run on the old release. . . icon_confused.gif

This code does work in the old release:
Code:
PARM DEBUG (STATE) ENVIRONMENT (COBOL) LIST (FILE PARM)       
DEFINE PKDFLD W 7 P 2 VALUE 0                                 
DEFINE DSCHCLD1 W 8 A  VALUE 'DSCHCLD1'                       
DEFINE SOME-VALUE W 12 A  VALUE 'SOME VALUE'                 
JOB INPUT NULL                                               
CALL DSCHCLD1 USING (SOME-VALUE)                             
STOP                                                         


This is the displayed output:
Code:
HELLO WORLD.
SOME VALUE   


This is the called cobol module (note the parm is not the same length of the ezt definition - intentionally):
Code:
       DATA DIVISION.                                                 
       WORKING-STORAGE SECTION.                                       
       77  WKS-MESSAGE         PIC X(23) VALUE                       
                                   'WORKING-STORAGE SECTION'.         
       77  HELLO-WORLD         PIC X(15) VALUE 'HELLO WORLD.'.       
      *                                                               
       LINKAGE SECTION.                                               
       01  PARM-AREA.                                                 
           05 SOME-PARM        PIC X(10).                             
      *                                                               
       PROCEDURE DIVISION USING PARM-AREA.                           
                                                                     
           DISPLAY HELLO-WORLD.                                       
           DISPLAY SOME-PARM.                                         
      *                                                               
       999-END.                                                       
           GOBACK.                                                   


You might try this simple test on your system and let us know what happens. . .

No, you do need to link the cobol module into a loadlib that is named in your joblib/steplib or is link listed.

Did you compile the cobol program i posted? If not, do so.

Did you use exactly the ezt code posted? Again, if not, do so.

Once these are done, post your jcl, ezt code, and the output from the ezt executon.

Hello,

Did you successfully call your "hello world" module from some other cobol program? If not, it would eliminate one more unknown to do so. Is the load module really named cobol2?

You posted the linkage secton at the bottom - any particular reason why?

Try removing the 1st easytrieve statement (list on). Also, please post the complete easytrieve output.

hi Dick,

I tried to execute the module after making the changes as you suggested.Still I am facing the same error.I am not getting any output other than the error stements listed in the last post.

The linkage section is only mistake happened while pasting it to the forum.

Kindly help.

Hello,

What happened when you tried to call your cobol subprogram from another cobol program rather than easytrieve?

You haven't posted the complete easytrieve output yet. . .

Maybe no more errors, but there is more output. . .

When some of us ask for things to be done, there are reasons. . .
