Ed, Next you will be wanting the register cross reference to indicate which half is referenced or changed. ;-)
I don't know how you managed to get the GR32/GR64 type checking to work for you. I tried it when it came out and ran into so many problems that I just use GR. It seems like half the HLASM APARs include fixes to the register type checking. And for me personally, I did not see the value in the GR32/GR64 checking anyway. On the other hand, the GR checking is of tremendous value because it flags all kinds of real errors. 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.
