My VSE assembler is rusty – What exactly does “CORG 0,256” do? I do not think “CORG” is a valid assembler directive in the HLASM product on z/OS.
From: IBM Mainframe Assembler List <[email protected]> On Behalf Of David Clark Sent: Monday, February 23, 2026 5:09 PM To: [email protected] Subject: Cache Alignment in CICS I have been aligning my assembler data areas and code areas with the following macro. CORG 0,256 But now I'm looking at an assembler program for CICS and I see that the alignment is off by 32 bytes. That accounts for the EAI stub that is linked onto the beginning of my program. I also see 56 bytes added on to the end of my program. What do y'all, that care about cache alignment, use for a program in CICS?
