Just exactly as you did right there. That's it! :-)

You don't have to compile it. IDL will find it and compile
it when it needs it. That is, when it gets to the statement
above in your code. Just put it in a file named glactc.pro
and make sure the procedure GLACTC is the *last* program
module in the file. (This will be true for most of the routines
you get from established libraries, but may not be true for most
of the routines you get from your buddies.)

Forget makefiles. Forget compiling. You are working with IDL now! :-)

Cheers,

David
