Thanks for the explanation. As stated in previous posts, I'm retired but I
continue to "work" on Don Higgins' z390 software, which is Java code that
emulates HLASM. Right now I'm working through the z390 implementation of the
built-in functions, making sure they behave as in HLASM. (Some do, some don't.)
The question about C2B came up when looking at C2B. I've just finished updating
the C2B code to (at least) match what is shown in the examples for C2B in HLASM
Language Reference. You might consider updating the examples to include
C2B('&&'). Probably all the other C2x examples as well.
