My PL/I code has the following:

dcl my_output file stream output;

If I had to run this program from a JCL I'd assign a DD to match this 'my_output'. But this program runs online (called from another via plitdli).

Question is: how do I assign the resources (input and output) when the program runs online instead of batch?

Thanks a lot!

if the program, as You say, runs online
You are out of luck, You cannot do any I/O operation on mvs files

The program is already running. Is online. Does use a file stream output. Are you sure IMS doesn't play a role assigning resources?

has the program ever executed the bit of code that writes to that file? Are there any writes to that file in the program?!

Actually, I can't say whether is a file or a printer or something else. But yes, there are PUTs to that file:
put file (my_output) skip edit ('DB2 SQL SEVERE ERROR') (A);

Has it ever been written to? Also, is the file OPENed in the program - if it has never been accessed then IMS will not know about it but it could be an abend waiting to happen.

The file is OPENed. Can't say if it has ever been written to.
I can't believe what you guys are telling me: you can't use file input and output from PL/I unless your program runs batch. I'm very new to PL/I and IMS, but that doesn't sound very reasonable to me. I'm not saying you are wrong, but confusion grows stronger and stronger in poor me.

Hello,

For this particular question, what does "online" mean?

The opposite to batch: no JCL involved.

Using IMS DC or CICS?
