If you do ".compile taco", IDL will search for a file "taco.pro" in your
path and compile it, recognizing all procedures and functions in the file.

If you do "taco, parameters, /keywords", IDL will search for a file
"taco.pro" in your path and compile everything until it finds a
PROCEDURE taco. Anything following that won't be compiled. A FUNCTION
taco won't be recognized.

If you do "result = taco(...)", IDL will search for a file "taco.pro" in
your path and compile everything until if finds a FUNCTION taco.
Anything following that won't be compiled. A PROCEDURE taco won't be
recognized.

So, make sure the function / procedure which has the same name as the
file is the last one in the file. This will normally be your "main"
function / procedure. If other functions / procedures are called
(needed) exclusively by that "main" one, put them into the same file,
but above. If any function / procedure might be needed more often, put
them into their own file.

Good luck,
Benjamin
