As a matter of fact, I'm currently writing a Motif application using the DEC
Motif package on VAX/VMS, using only a Motif textbook written for UNIX.

The Motif package is pretty good; the only thing missing that I've seen is
the XtSetArg function. However, setting the Arg array is pretty easy once
you get the hang of it. Callbacks are a little tricky, since Motif requires
everything to be passed by address (so some type checking is lost). However,
as log as you remember to pass strings aroung as a C_Types.Char_Ptr (C_Types,
along with Motif, are in the ADA$PREDEFINED directory), it's not hard to
work out the interface.

One other thing to remember: I couldn't find any examples in the ADA$EXAMPLES
directory that actually use the Motif package. They all use their own binding
to X and Motif.

Good luck!
