... which links to a "Fix Readme" with recommendations
for dealing with possible clashes between 30 new
instruction mnemonics and customer-defined macro names.
One suggested remedy is:
If the macro names cannot be easily changed, then
the programs can use the ":MAC" suffix to ensure that
the macro is used rather than the instruction.
Would defensive programming recommend that all macro
invocations use the ":MAC" suffix lest a name become
an instruction mnemonic in the z17?
An alternative not mentioned might be if references
are numerous to COPY the affected macro definitions
into source programs.
