COMPILE JCL FOR COBOL

STEP1 - COMPILING COBOL PROGRAM

 //jobname JOB (acctno),name,MSGCLASS=1                 (1)
 //stepname EXEC PGM=IGYCRCTL,PARM=(options)            (2)
 //STEPLIB DD    DSNAME=SYS1.COB2COMP,DISP=SHR          (3)
 //SYSLIN   DD   DSNAME=&SRCEIN,UNIT=SYSDA,             (4)      <-- OBJECT
MODULE O/P
 //              DISP=(MOD,PASS),SPACE=(subparms)
 //SYSUT1   DD   UNIT=SYSDA,SPACE=(subparms)             (5)
 //SYSUT2   DD   UNIT=SYSDA,SPACE=(subparms)
 //SYSUT3   DD   UNIT=SYSDA,SPACE=(subparms)
 //SYSUT4   DD   UNIT=SYSDA,SPACE=(subparms)
 //SYSUT5   DD   UNIT=SYSDA,SPACE=(subparms)
 //SYSUT6   DD   UNIT=SYSDA,SPACE=(subparms)
 //SYSUT7   DD   UNIT=SYSDA,SPACE=(subparms)
 //SYSPRINT DD   SYSOUT=*                               (6)
 //SYSIN    DD   DSNAME=dsname,UNIT=device,             (7)      <--- ATTENTION ,
HERE WE GIVE SOURCE PROGRAM
                     VOLUME=(subparms),DISP=SHR



(1) This step indicates the starting of job.

(2) This step specifies compiler IGYCRCTL is to be invoked.

(3) This DD statement defines the data set where compiler resides.

(4) The SYSLIN DD statement defines the data set (the object module) will be
passed to LINKEDIT step

(5) The SYSUT DD statements define the data sets that the compiler will use
to process the source program.
    All SYSUT files must be on direct-access storage devices.

(6) The SYSPRINT DD statement defines the data set that receives output.

(7) The SYSIN DD statement defines the data set to be used as input to the
job step (source code).



STEP2 -   LINK EDIT

     //LKED       EXEC PGM=IEWL,REGION=1024K,PARM=(options)    (1)
     //SYSPRINT   DD   SYSOUT=A                                (2)
     //SYSLIB     DD DSN=SYS1.COB2LIB,DISP=SHR                 (3)
     //           DD DSN=SYS1.COB2COMP,DISP=SHR
     //SYSLMOD DD DSN=MYDOC.MYPROG.BLM(TESTTEMP),           (4)    <--- LOAD
MODULE o/p
     //              DISP=SHR
     //SYSUT1 DD    UNIT=SYSALLDA,DCB=BLKSIZE=1024,         (5)
     //       SPACE=(CYL,(1,1))
     //SYSTERM DD SYSOUT=*
     //SYSPRINT DD SYSOUT=*
     //SYSLIN    DD DSN=&LOADSET,DISP=(OLD,DELETE)          (6)    <--   OBJECT
MODULE i/p
     //SYSIN     DD DUMMY



(1) This step specifies IEWL will be invoked

(2) The SYSPRINT DD statement defines the data set that receives output.

(3) This step specifies system datasets

(4) SYSLMOD DD statement defines the dataset , where load module to be stored

(5) to process object module, IEWL will use these units

(6) SYSLIN DD statement defines the dataset, we will give OBJECT MODULE here
as an input to IEWL



---------------------------------------------------------
 compiler options
---------------------------------------------------------

Some of IMPORTANT compiler option , when compiling COBOL program

1. QUOTE/APOST
   Default - QUOTE

   If we used QUOTE, figurative constant [ALL] QUOTE or [ALL] QUOTES to
represent quotation mark (")
   If we used APOST, figurative constant [ALL] QUOTE or [ALL] QUOTES to
represent one or more apostrophe (') characters



2. NUMBER/NONUMBER
   Default- NONUMBER

   If we used NUMBER, line numbers in source code will be displayes in error
messages and listings
   If we used NONUMBER, line numbers in source code ignored by compiler, and
it generates sequence
   number for that source



3. LIST/NOLIST
   Default - NOLIST
   LIST, produce listing of assembler-language expansion of program (is used
to SOC07,SOC04 solving)
   NOLIST, it wont produce compiler listing


4. MAP/NOMAP
   Default - NOMAP

  MAP, to produce listing items defined in DATA DIVISION.
  NOMAP, wont produce listing




RUN JCL

//ASD220X JOB (03SES,SSEA),'RUNJCL',CLASS=S,MSGCLASS=T,
//            NOTIFY=&SYSUID
//STEP1    EXEC PGM=TESTTEMP                <- LOAD MODULE name
//STEPLIB DD DSN=MYLIB.TEST.BLM,DISP=SHR    <- Data set where LOAD MODULE
resides
//SYSIN    DD *                             <- Data passing to that program
(optional)
0000002222
/*
//SYSOUT   DD SYSOUT=*
