The easiest way to get around this is to put functions that are
referenced by other functions earlier in the source code, before the
functions that reference them. In this way, they are compiled first.
If you are going to use the forward_function statement, I think
you have to give it global scope (don't put it within the context
of a function). Just an idea, I've never used this statement. I've
just always made sure functions which are called later on in the
source file appear first.

I ran this little snippet of code that you provided, and it worked
exactly as expected. I'm running IDL v4.0.1 on SunOS 4.1.3. You did not
mention your OS or IDL version... perhaps that has something to do with it.

I got the following result, as expected:
idl>.run ~/idl/get_data
idl>print,get_data( 1 )
test structures
idl>
I'm not sure this is much help to you, but there you have it.
