Re: Changing DISPosition on the fly

Try reading IEA2A832 z/OS V1R4.0 MVS Auth Assembler Services Guide:

Chapter 25. Dynamic Allocation
Chapter 26. Requesting Dynamic Allocation Functions

Look for the deallocation call point. You may need to free, realloc with
new disp and then free again.

I have a program which creates a number of datasets. One sequential data
set is not required in certain error circumstances and I want to change
the
disposition from (NEW,CATLG,DELETE) to (NEW,DELETE,DELETE) on the fly.

ISTR that this is possible by modifying the DCB or JFCB but RTFM and
searching the archives hasn't given me any leads.

Any ideas/hints gratefully received.

I know I can set a return code and have an additional step to do the
delete,
but that means finding and changing PROCS over which I have no control.

tia,
