Hello,
When i am trying to execute the "say exec " in the link provided
I am getting an error " command ivprexx not found."
i just pasted the same program and tried to execute it.

1. Do we need to add on something or prepare a jcl which will
execute this rexx program
2. What is DFSREXX0 . How to provide this.
3. What is IVPREXX.

Regards,
Laks.

Hello ,

I am really sorry that i am posting the same query as previous one.
Actually i didn't understand how to use ims adapter for rexx.
Do we need some third party tool to be installed in the mainframes
for executing and rexxwith ims pgm.If somebody having some basic
sample code for it ,plz post it.

Thanks & Regards,
Laks.

IVPREXX is a rexx and can be found in the IMS library with the suffix DFSEXEC
DFSREXX0 is a compiled version of IVPREXX and must be made available either through the LINKLIST OR STEPLIB.

Hello,

Thanks nevilh,for telling. I have one more simple doubt.
Can we execute any pgm(rexx with ims) by command
" ivprexx member-name". If it so then we can give PSB AND DATASET
NAME in rexx pgm itself.,
or do we need to prepare some jcl.

Thanks a ton in advance.
Laks.

Found this in the manual
REXX does not require a special PSB generation to add an EXEC and run
it because EXECs can run under a standard PSB (IVPREXX or one that is
established by the user).
and

The REXX environment executing under IMS has the same abilities and
restrictions as those documented in the TSO/E Version 2 Procedures
Language MVS/REXX Reference. These few restrictions pertain to the absence
of the TSO, ISPEXEC, and ISREDIT environments, and to the absence of
TSO-specific functions such as LISTDS.

Seems you should be OK
