It is not particularly good programming style to do this, and hence I
use it all the time! :-)

Here is you you do it:

pro mypro, arg1, arg2

  arg1 = arg2 + 5
  ... etc
@myinclude.pro

  return
end

Note that the standard path is consulted in including myinclude.pro,
otherwise it should be in your current directory.  Text is included
from the file verbatim.  In the example above, @myinclude.pro appears
within a procedure.  Therefore, myinclude.pro should contain neither a
PRO or FUNCTION declaration, nor a final END statement.  Works the
same as a C #include directive.

Happy programming,
Craig
