Hi all
I am doing the reverse engg on one of the REXX program and it contains one statment mentioned below.
"EXECIO * DISKR HEADER (FINIS STEM HEADER."

It doesnot have any ALLOC before this EXECIO. Even in the whole program there is no ALLOC on the HEADER........
Can somebody explain me that what this line will be doing in the program

Thanks in advance
Saurabh

EXECIO, even though it's enclosed in quotes, is an intrinsic REXX function that allows for file I-O.

ALLOC is not. It is a TSO (or MVS) function used to allocate a dataset or SYSOUT to a specific DD. It is certainly not required for a REXX exec to use.

My best guess is that the file allocations are handled by the invoking job, as they should be. Or, the ALLOC for the file is being handled elsewhere.
