Re: Allocating PC numbers
If you aren't using AXSET you certainly don't need AXRES. And many use AXSET with an AX of 1 (a special value), and don't use AXRES.

Re: Allocating PC numbers
Use the LXRES service. Then all you need to do is figure out how you want to "publish" your PC number to its potential users.

Re: Allocating PC numbers
Thanks Peter. I have been running my test program (that I got from somewhere) and realized that I was off-base with my understanding. I am also coming to understand that some of the stuff done by the program was not needed or incorrect, but still worked. For instance, it does an AXRES, followed by an LXRES and ETDEF. I don't see any reason for the AXRES. Maybe I am still not reading everything right.

Are, do you do some sort of loop checking to see what is free? I'd answer "no, not at all like that". You (the PC-owner-to-be) have to have reserved a linkage index (LX, via LXRES). The LX defines the "left part" of the PC number. You define/create the entry table and associate it with the LX (ETDEF, ETCRE, ETCON). The Nth entry (0-origin) in the entry table would correspond to a PC number with N as the "right part". N is the "Entry Index" (EX). A number is "free" if your entry table does not have enough entries to reach that number. The extended addressability guide is your friend.

It's possible to leave gaps if you want to create ranges for more complex products. Since the LX gets merged in, the numbers are system unique. -- Phoenix Software International Edward E.

Allocating PC numbers
When on z/OS and you want to create a PC routine, how do you determine what PC number the new routine is going to use? Is there a list of 'used' ones somewhere? Are, do you do some sort of loop checking to see what is free?
