In the ooRexx Reference, see section 7.4.52 under "Builtin functions."
The first argument is the name of the routine in the library.  I
couldn't get it to work, though.

  Say RxFuncAdd('SysCls', 'rxwinsys', 'TryCls')
  /* says 0, which should mean success, but: */

  Say RxFuncQuery('TryCls')
  /* says 1, which means not found */

  Say 'TryCls'()
  /* error 43.1, routine not found */

If you want to load *all* the routines in the rxunixsys module, using
their original names, you can use a ::REQUIRES directive instead:

  ::Requires rxunixsys library
