What page in the HLASM ref are you referring? I only asked you to show some evidence you are right but you continue to refuse. You've told me that application programs can be more complicated than system programs. What at the IRS is so complicated that it needs 8 assembler programmers? What makes it difficult for these programs to be written in cobol? What is it that you do that is more complex than a basic assembler program?

Not HLASM. Show us the page in the HLASM reference that tells us about addressability (not the simple base/offset calculations in the addressing section). Show us where in HLASM ref from 2004 https://publibz.boulder.ibm.com/epubs/pdf/asmr1010.pdf that it documents instruction syntax for AR mode, primary, secondary, shared memory, access registers, 64 bit addressing, instructions specific to addressability, authorization and much more. As for expressions, this has nothing to do with addressability and everything to do with calculating base reg and offset. Show us in the HLASM ref that it is anything different.

You are describing various methods for calculating offset, base and index. Only POPS tells you about the syntax. Assume you don't know the LH instruction and don't have the POPS. Using only the HLASM manuals, what is wrong with LH R3,R1? A true HLASM programmer relies heavily on POPS.

Consider LH R3,SYSPRINT+DCBLRECL-IHADCB(R4) USING SYSPRINT LH R3,DCBLRECL Both of these use things that aren't in PoOps. And, no, I'm not talking about the DCBD expansion. ________________________________________ From: IBM Mainframe Assembler List <[email protected]> on behalf of Jon Perryman <[email protected]> Sent: Wednesday, June 28, 2023 5:44 PM To: [email protected] Subject: Re: Variable symbol without leading & Seymour, you said that POPS does not explain how to symbolically encode instructions. What other manual tells you how to code instructions? Tell us where the MVC instruction is documented outside of the POPS? I used PLO as an example because anyone can code MVC without looking at the manual. if the POPS incomplete, then contact IBM to correct the POPS. For me, PLO was adequately described for using it correctly. On Wednesday, June 28, 2023 at 02:21:25 PM PDT, Seymour J Metz <[email protected]> wrote: Water is wet. There is no need to refute claims that nobody made. PLO?

For instance, what manual tells me how to code the PLO instruction with multiple syntax variations. As for pseudo-ops, they do not generate machine code but instead are assembler control statements (e.g. eject). As for mnemonics, only a few are specifically documented in the HLASM reference (e.g. BNZ and JNZ). The vast majority of mnemonics are macro's documented in product specific manuals and to a small extent OPSYN. The classic example is the toolkit replacing branch instructions with jump instructions.

It explains instruction formats and semantics; it does not explain how to symbolically encode them, much less explaining all of the pseud-ops. ________________________________________ From: IBM Mainframe Assembler List <[email protected]> on behalf of Charles Mills <[email protected]> Sent: Wednesday, June 28, 2023 2:03 PM To: [email protected] Subject: Re: Variable symbol without leading & The "other manual" for the Assembler is Principles of Operation. If you want to know how COBOL MOVE works, you look at the COBOL Language Reference. But if you want to know how MVC works, you don't look at an assembler manual, you look at Principles.

I find the distinction rather arbitrary - both aspects of HLASM are intimately interconnected. As Mr. Metz correctly remarked, there is only a single Language Reference Manual for HLASM.
