I do my major coding on my pc using the Dignus Assembler. I was moving some working source code to z/VM where production assemblies are performed and am having trouble finding the correct optcode table for the following instructions: CHSI MVHHI CHHSI
We have the following HLASM installed: HLASM R5.0 2011 (PTF UK31916) I have tried: YOP ZOP ZS3 ZS4 does not work on our HLASM. First, what is the correct OPTABLE() setting for these instructions? Second, I thought the halfword-Imm instructions were available all the way back to the MP3000 days. Am I wrong? Third, in the assembler manual, they state: "The operation codes supported by High Level Assembler are described in the documents listed under “Related Publications (Architecture)” on page 451." Which manual in that section is it refereeing to? None of them seem correct from the title. -- Tony Thigpen
