How do you run a rexx program through JCL?

Answer 1

This is the simplest form: no files are allocated for EXECIO.

All REXX features are available.

All REXX functions are available, including EXECIO.

All TSO commands are available,

for example: DELETE, LISTCAT, HRECALL, HDELETE.

ISPF features are not available,

for example VGET, File Tailoring. //* job statement //TSOBATCH EXEC PGM=IKJEFT1A,DYNAMNBR=200 //SYSEXEC DD DSN=userid.REXX.EXEC,DISP=SHR //SYSPRINT DD SYSOUT=* //SYSTSPRT DD SYSOUT=* //SYSTSIN DD * PROFILE PREFIX(userid) /* please use this,*/ /* specifying your userid*/ %MYREXX

Same as the previous, but two files are allocated for EXECIO

The program uses EXECIO.

It reads the file defined by //INFILE

it writes to the file defined by //OUTFILE

Do not use an ALLOC command for these files in the REXX program! //* job statement for invoking rexx by jcl //* good example of TSO in Batch //* how to run a rexx program with job control language //TSOBATCH EXEC PGM=IKJEFT1A,DYNAMNBR=200 //SYSEXEC DD DSN=userid.REXX.EXEC,DISP=SHR REXX program library //SYSPRINT DD SYSOUT=* //SYSTSPRT DD SYSOUT=* //INFILE DD DSN=userid.MY.INPUT,DISP=SHR //OUTFILE DD SYSOUT=* //SYSTSIN DD * PROFILE PREFIX(userid) /* please use this,*/ /* specifying your userid*/ %MYREXX
