I did not realize that one of your objections was having to code x'40' when what you meant was c' '.
>From the feedback I got, LFI R15,C' '*ShiftLeft24 should work but LFI >R15,C'A'*ShiftLeft24 will not due to overflow. What about &Z SETC BYTE(0) LFI C' &Z.&Z.&Z' I am not a proficient macro language hacker. Will the above compile? If not, will something like that?

I consider LFI R15,X'40000000' to be ugly, and would like to be able to either use an immediate field combing CL1 and XL3 pieces or to refer to an EQU defining that combination. Is there any way to do that in HLASM? -- Shmuel (Seymour J.) Metz http://mason.gmu.edu/~smetz3 עַם יִשְׂרָאֵל חַי נֵ֣צַח יִשְׂרָאֵ֔ל לֹ֥א יְשַׁקֵּ֖ר
