If you are running your REXX in batch, any DDs and DSNs that are not
coded in the JCL can be allocated (and then deallocated) in REXX itself,
e.g. as:
IF SYSDSN(DSN) = "OK" THEN
"ALLOC FI("||FILE||") DA("DSN") SHR"
(where 'DSN' exists and is generated with a date/time-stamp in it, and
'FILE' is whatever DDname this DSN is to be associated with.)
Next, invoke your program from your REXX. It will use the DDs and DSNs
already hard-coded in your JCL + also those allocated in your REXX.
Finally, code
"FREE FI("||FILE||")"
after your program has executed and before your REXX terminates (or let
MVS deallocate it for you at end of jobstep, if you prefer).

Hi Elardus,
There is a dataset which get updated every hour in our production system,
actually i need to ftp that particular dataset every one hour.
For now i'm submitting the job manually by changing the date and time for
every one hour.
I'm not clearly aware of wildcard datasets that can be given as a input DSN
in JCL.
Input dataset name is same, but I need to get output using wildcard in JCL
with different time on hourly basis.
for example, in ftp sysin----> *//PUT 'default_file_name' date_time.txt*
date_time.txt should be like 140727_0900.txt @ 09:00 AM
If possible kindly let me know wildcard details for REXX program, this may
be useful for me in future.

What wildcards? Please give examples. Lizette Koehler also asked for
examples/samples.
I need to get an extract file for every one hour and I need to add the
job in OPCA, so that by using wildcard characters for every one hour the
extract may get genrated automatically.
Just what wildcards for hourly works? Your request is too wide for us to
interpret. is it Dataset names, input in source DD? etc?
Please let me kow the detailed explanation i.e. wildcard characters that
is found in JCL to describe a dataset.
You cannot use wildcards in a JCL for dataset, only symbols which can be
substituted by SET statements or z/OS symbols.
Only possible wildcards for datasets are in RACF profiles or DFDSS
statements or such and then only in SYSIN or such DD statements.
You can always use Automation package or write out a
REXX/Assembler/COBOl/etc program to expand wildcards to fully expanded
datasets.
