IMHO it is cleaner and more readable to do
L R15,=V(ENTRY)
The other code is not only a Rube Goldberg, but it has a 50/50 chance of
blowing up; V(ENTRY) has full word alignment.
Of course, on current processors there are better options.
BTW, is there some way to get the offset of an external dummy ("pseudo
register") into the displacement without resorting to an ORG?

Subject: Loading a VCON with as an immediate value
To me, it seems silly to do the following, if I am only loading a VCON in a
single place.
L R15,=V(ENTRY)
When I can do:
LLILF R15,0
ORG *-4
DC V(ENTRY)
I am hoping that someone out there can tell me how I can improve the
previous 3 instructions to be something like:
LLILH R15,ENTRY
HLASM complains the ENTRY is either relocatable or unresolved. Yes, it is
relocatable, but at run time it will be a constant. Is there some "magic"
to get HLASM to know this?
