CALL_EXTERNAL with DEFAULT keyword in IDL [message #268]

Hi,

I am trying to call some external C functions from inside IDL running on VMS.
Since now I succeeded to run:

d=CALL_EXTERNAL("LOGICAL_NAME", "functionName", param)

after having defined the LOGICAL_NAME in this way:

$ DEFINE LOGICAL_NAME user$disk:[idl.silvio]filename.exe

where filename.exe was linked with the usual

$ link filename,SYS$INPUT/OPT/SHARE
UNIVERSAL=functionName^Z

I would like to use the DEFAULT keyword of CALL_EXTERNAL, so to avoid defining the LOGICAL_NAME every time, but since now I can't figure how to make it work.
In fact all of my tried turned unsuccessful.

Being new to VMS and IDL, I would gladly accept any help.

Email replies or post.
Thanks in advance.
