Gav,

Maybe I'm missing something but if your 'formula' is fixed then you
don't need execute at all, you can just write:

speci=where(mr[*,*,159] le 8 or $
mr[*,*,170] gt mr[*,*,159] or $
mr[*,*,235] gt mr[*,*,159],speccount)

Execute is only required when the code you're going to be running isn't
known at compile time. For instance if you had an interactive program
where a user could type IDL syntax into a text widget or at the command
line.

Thanks,

Allan
