I have a REXX used to read/write file use command EXECIO. It is wokring fine when I submit it foreground using EXEC.

But when I submit the REXX from jcl.

//STEP010 EXEC PGM=IKJEFT01
//*
//SYSEXEC DD DSN=MYLIB.TEST.REXX,DISP=SHR
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD *
REXXmembername

The system always tell me :

DATA SET MYLIB.TEST.DATA ALREADY IN USE, TRY LATER+

comment: MYLIB.TEST.DATA is the lib used to hold files.

Can someone analyze what could be wrong?

Thank you.

Giving more clear message:

/* REXX */
....
DSNAME1 = "'"MYID008.TEST.OUTPUT"'"
DSNAME2 = "'"MYID008.TEST.DATA || "(DATA3)" || "'"
status1 = SYSDSN(DSNAME1)
say 'status1 = ' status1
status2 = SYSDSN(DSNAME2)
say 'status2 = ' status2
....

Scenario 1: submit using EXEC

status1 = OK
status2 = OK

Scenario 2: submit from jcl (as show above)

status1 = OK
status2 = UNAVAILABLE DATASET

Why submit from JCL get different result? How to solve it ?

Thank you.

Well, using your example JCL and REXX exec, and just replacing your dataset high-level qualifier (MYID008) with my own, it worked the same way in both environments for me:

status1 = OK
status2 = OK

Did you try to activate a trace (TRACE I) and see what it shows?

Hello Superk,

Thank you for your reply.

Sorry, It is working ok on both way today. I did not change anything. I am confused. Anyway, can you tell me what 'trace' mean? How to use it?
