Another example of a use for OPSYN is if you are debugging something
that has PRINT NOGEN / PRINT OFF, and you don't want to modify the
macros to remove them, you can just OPSYN PRINT to something else and
use an inline PRINT macro that does nothing.

I doubt if anyone uses OPSYN to do things like change AR into ADDREG
or something (at least I hope not...)
