No, it then applies only to the main level (I tested it once). If it
would apply to all routines, then it would immediately break any code
in the big libraries that you might be using.

It is a very good idea, in my opinion, to start each and every routine
with "compile_opt idl2". This not only enforces square bracket array
subscripting, but also makes long integers the default. This prevents
FOR-loop problems like in yesterdays thread "From a novice in IDL".

cheers,
Jaco
