Makes perfect sense, once you dig a bit deeper into ASSEMBLER macro language.

The distinction between SETx as a macro control statement and EQU as a "model"
statement to be "thrown out" by the macro processor should be clear after the
first two or three macros you write.

And the flexibility I personally experiences when migrating from ASSEMBLER XF to
ASSEMBLER H. Lots of restriction of ASSEMBLER XF macro language suddenly were
relieved, sometimes in a manner I couldn't understand how it is implemented.
This came due to the merging of the early phases of "ordinary" assembly into the
macro phases, so the macro processor had knowledge of attributes of symbols that
ASSEMBLER XF macro processor hadn't.

Kind regards

Bernd
