How to copy a module several times

Postby koalapowah » Thu Dec 12, 2019 5:00 pm

I need to copy one module from one PDS to other PDS, but the name had to be the same and the content had to be the same module n times inside.

Could you help me?

Member names have to be unique. You could possibly use generation if the copied to dataset was a PDSE.
The problem I have is that people can explain things quickly but I can only comprehend slowly.

Just exactly what do you mean by "...and the content had to be the same module n times inside."?

Interpretation 1 - A library containing three copies of the same load module, but with 3 different names

Interpretation 2 - A single load module with several copies of one module with different names, since you cannot have 2 modules with one name.

The following JCL can achieve both interpretations.
//A       EXEC PGM=IEFBR14
//XLOAD    DD  DISP=(MOD,DELETE),UNIT=SYSALLDA,SPACE=(TRK,0),
//             DSN=&SYSUID..PVX.XLOAD
//SYSTSPRT DD  DISP=(MOD,DELETE),UNIT=SYSALLDA,SPACE=(TRK,0),
//             DSN=&SYSUID..PVX.SYSTSPRT
//B       EXEC PGM=IEBCOPY
//SYSPRINT DD  SYSOUT=*
//I        DD  DISP=(SHR,PASS),DSN=&SYSUID..PVX.LOAD
//O        DD  DISP=(,CATLG),UNIT=SYSDA,SPACE=(TRK,(2,2,1),RLSE),
//             DSN=*.A.XLOAD
//SYSIN    DD  *
 C I=I,O=O
 S M=PVX
 C I=I,O=O
 S M=((PVX,PVXCOPY1))
 C I=I,O=O
 S M=((PVX,PVXCOPY2))
//C       EXEC PGM=IEWL,PARM='MAP,LIST'
//SYSPRINT DD  SYSOUT=*
//I        DD  DISP=(SHR,PASS),DSN=&SYSUID..PVX.LOAD
//SYSLMOD  DD  DISP=(OLD,PASS),DSN=*.A.XLOAD
//SYSLIN   DD  *
 INCLUDE I(PVX)
 CHANGE PVX(PVXCOPY1)
 INCLUDE I(PVX)
 CHANGE PVX(PVXCOPY2)
 INCLUDE I(PVX)
 ENTRY PVX
 NAME PVXCOPY3
//D       EXEC PGM=IKJEFT01
//STEPLIB  DD  DISP=SHR,DSN=&SYSUID..LOAD
//SYSTSPRT DD  DISP=(,CATLG),UNIT=SYSDA,SPACE=(TRK,(1,1)),
//             DCB=(RECFM=VB,LRECL=120,DSORG=PS),DSN=*.A.SYSTSPRT
//SYSTSIN  DD  *
LISTPDS (PVX.LOAD PVX.XLOAD)
LMATTR (PVX.XLOAD(PVX) PVX.XLOAD(PVXCOPY1) PVX.XLOAD(PVXCOPY2) +
PVX.XLOAD(PVXCOPY3))
//E       EXEC PGM=PRINTDS
//STEPLIB  DD  DISP=SHR,DSN=&SYSUID..LOAD
//SYSPRINT DD  SYSOUT=*
//SYSUT1   DD  DISP=OLD,DSN=*.A.SYSTSPRT

Step A deletes any previous examples of two data sets.

Step B copies module PVX, with 3 load module names.

Step C builds load module PVXCOPY3, with several copies of module PVX.

Step D runs several TSO commands in batch to list the data set constructed in steps B and C. The LMATTR and LISTPDS commands are private TSO commands as is the PRINTDS program in step E.

Step E prints the output of step D. This is the output.
