The biggest drawback to GR32/GR64 checking, even if it was correctly implemented, is that the assembler does not know the AMODE so does not know if LA or MVCLE reference 32 or 64 bits of the registers.
It's understandable that GR32 is used for modal instructions. It's rather unfortunate that GR64 is not accepted. It would be better if both GR32 and GR64 were accepted. There are only a handful of modal instructions. The same goes for any base register reference. -- Edward E Jaffe Phoenix Software International, Inc 831 Parkview Drive North El Segundo, CA 90245 310-338-0400 x318 [email protected] http://www.phoenixsoftware.com/
