hello every one .
i have a question i write a rexx to save all dataset start with (ucat ) means ucat* and retrieved informaiton (Tracks, %Used,XT,) and if their XT is larger than 16 save them in output file.

i write a pgm to do that when execute it it woprks but when run it by jcl is returned max-rc 0 but didnt work and dont allocate empty output file :

here is my code :

rexx:

/* REXX */

TRACE OFF

I=0
X=1
USEDSN="'DBKISA3.REP.OUT'"

Right off, part of the problem I see is that you're using ISPF services (ISPEXEC) but nowhere in your JCL have you setup and started an ISPF environment.

As pointed out by MrSpock, you are using ISPF services, but your JCL do not allocate required ISPF dataset, nor does your parm specify ISPSTART CMD(name).
Something else, it looks like you are missing a RETURN before the ALLOCATE_TEMP_DATASET: label, so I will expect your temp ds to reallocated when you do not expect it.
Last, but certainly not least, please use the CODE tags, your program is rather hard to read due to lack of indentation.

Sample JCL

I admit that I am not very fond of the expression "ISPEXEC ....". I much prefer either
