With due respect for assembler programmers, why would anyone write a program to do this? icon_eek.gif

I agree and don't understand this requirement at all.

There are already IBM utilities in-place and available to do this.

I'm light on REXX, but I think it can do it as well.

Why reinvent the wheel?

Do you have an Assembler background?

If not, then it would be ill advised.

Homework, perhaps?

Mr. Bill

We got this requirement to allocate 1000 files which is provided in a PS file as DSN name and VOLSER number......

Any how, I have coded successfully with PeterHolland's hint.

The logic is as follows

LOCATE INDAB
LTR 15,15
BZ CATLOGED

INDAB CAMLST NAME,FILE,,LOCAREA
FILE DC CL44'a.b.c'
LOCAREA DS 0D
DS 265C
