Oh my gosh, @John, 4 bytes of virtual storage is NOTHING! Especially now that there is no effective 4K limit on easy addressability.
OTOH, you have already spent the most precious thing of all on it: your time. Not to mention whoever has to maintain this code, is probably a newbie to HLASM, and has to puzzle over the ORG and VCON. Yes, what is slightly more than nothing is the cache line, and using LARL avoids the hit on the data cache.

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? -- Money is the root of all evil. Evil is the root of all money. With that in mind, money is made by the government ... Maranatha! <>< John McKown
