Curious variable in xmfonts.mod

Recommended Posts

I'm trying to learn how to write X programs.  At the moment, I'm playing with samples/X11/smfonts.mod

I've figured some things out, like fixing  the \n and \0

One thing I'm wondering about is in the CreateHelp procedure:

VAR
 button:            Xt.Widget;
 message_box:            Xt.Widget;                     (* Message Dialog *)
 args:                  ARRAY [0..MAX_ARGS] OF Xt.Arg; (* arg list       *)
--  message:            ARRAY [0..1023] OF CHAR;
 title_string:            Xm.XmString;
 message_string:      Xm.XmString;
 button_string:      Xm.XmString;

What, precisely, is: --  message         ?

I originally thought it might be extraneous characters due to the focus policy of Waimea - but the compiler didn't complain.  I then tried removing them and did receive an error (though there is a possibility that it was related to an erroneous paste that duplicated it a few lines down in the code).

Anyone know what the two hyphens are for?

Well, just so it looks like people actually read the board, I'll point out that someone told me that it is most likely a C++ comment

Now, off to start another topic :)
