and this is the impoortant point that needs to be made here. In, general, of course, there are interactions. The formats of constants defined in DC statements are, in fact and appropriately, defined in the HLASM Language Reference. In general, while machine-instruction formats are defined in the PrOp, assembler-instruction formats are defined in the HLASM LR; and both are needed to write an HLASM routine. Tom's statement is thus entirely correct but a little incomplete.
