The above Rexx can also be executed from within a job(JCL) as shown bellow:

//************************************************
//STEP010 EXEC PGM=IKJEFT01,DYNAMNBR=75
//SYSPROC DD DISP=SHR,DSN=Your-REXX-Library
//SYSTSPRT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SYSTSIN DD *
YOURREXX-NAME
/*

Common Errors:
1)
Job abended with MAXCC=12.
spool information in SYSTSPRT

+++ S_RC = RXSUBCOM('ADD','DSNREXX','DSNREXX')
Error running YOURREXX-NAME, line 62: Routine not found

You may have to add a SDSNLOAD library(that contains a member RXSUBCOM) to joblib in your JCL.
e.g.
//JOBLIB DD DSN=ssidPRD.ssid.SDSNLOAD,DISP=SHR


Enjoy Rexx.
