What about (untested)
ShiftLeft24 EQU x'1000000'
LFI R15,X'40'*ShiftLeft24

Subject: Complex immediate fields
Back in he Assembler XF era I would code something like
LA R0,L'DEST
LA R1,DEST
XR R15,R15
ICM R15,8,=C' '
MVCL R0,R14
On current hardware there is an IILF (LFI) instruction, and I would like to use
it instead of the XR/ICM sequence. 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?
