** This looks strangely like lib$get_input.  However, if you define a 
** foreign command, you can type parameters after the program invokation,
** and have the program retrieve them.
**
** For example, if you compile this program to DISK:[DIR]LIB_GET_FOREIGN.EXE,
** you can say:
**
**    $ TEST :== $DISK:[DIR]LIB_GET_FOREIGN
**
** and then run the program like this:
**
**    $ TEST PARAM1 PARAM2
**
** which should produce:
**
**    Input was: "PARAM1 PARAM2"
**
** If you don't specify parameters, the program will just behave like
** lib_get_input.c
