How IMS picks up PSB at run time

HI,
i have a doubt regarding IMS psb's .

there is a IMS PROGRAM 'A'

A calls another IMS program 'B'. (dynamic call)

while running Batch job ,
i have mentioned the PSB FOR 'A' in dfsrrc00 parms.

I gave the PSBLIB library for 'A' .

This PSBLIB doesnt contain PSB for 'B'.
what will happen.........

thanks in advance

Try it......the other thing is that why are you dynamically calling pgm B? Is it a date routine that gets updated frequently? Otherwise, it is much more IMS efficient to link statically. However, you must consider the trade-off.....

Sometimes, you just do not have the background to ask a question. That is exceptionally frustrating. Other times, you have exhausted your research options and are literally banging your head against the wall. Mostly, you learn from your mistakes and these are lessons that you will never forget. Do not be afraid to experiment - except in production - you will learn a lot.

For instance - can you tell me how you would get a GE (not found) on an ISRT call? Years and years ago, when people were teching me - this is a question I would ask them in return.

If you understand that where you are in the database is essential, then you will have the answer. Don't just learn to do calls - learn how IMS works!
