That what I use, but I typically have a nonzero length, so it's
LFI Rx,X'40000000'+L'y

It's not clear whether you're assuming 31-bit or 64-bit mode. If it's only
31-bit, then IILF (also known as LFI if you have a recent maintenance level of
HLASM) would probably be best as a hardware solution, and you can write the
immediate value as follows if you like:
LFI R15,C' '*X'1000000'

Subject: Loading the pad byte for MVCL
So, I was wondering if anyone had a "better" way.
I've done:
IC R15,C' '
SLL R15,24
and
LGFI R15,X'40000000'
and
LY R15,PADCHAR
...
PADCHAR DC C' ',X'000000'
What I'd like is to do something like the LGFI (or LLILH) but using the more
"self documenting" PADCHAR format.
I'm probably just too picky. I could probably write a SETPAD macro and use
SLL, just haven't tried that yet.
