Even as a colleague and fellow assembler novice decades ago wrote
macro ZI, to do:
NI &1,255-&2
(try "grep ' NI .*,255-' SYS1.MACLIB/*" to see the motivation.)
And ever since I've wished that even in the absence of "PRINT GEN"
the assembler would display the generated hex on the line of the
macro call that generates exactly one instruction. I did this in
an assembler I wrote once; my clients, all MVS partisans demanded
I remove the feature.
