The -inlist()- function might possibly be useful here, if the macros'
names are not very long, and if there are not too many of them. In
Stata, type

whelp function

for help on functions (such as -inlist()-).

I hope this helps.

simpler way to test whether `a' is equal to any of the
other macros b-z than: `a'==`b' | `a'==`b' | ... |
