Re: Conditional compilation

Ron,
Great job filling in the blanks in my question - you hit the nail on the
head. I was trying to compile conditionals within a colon definition,
and your help gets me over a big hurdle that was in the way of
generalizing my code for several applications. The one instance that I
mentioned that worked, was not inside a colon definition. After several
years working with SwiftX, it is about time I understood what is going
on during compilation.

Leon, do you see any problem with using [ BarrVer 0= ], as Ron
illustrated below?
        
Thanks again,
David Graham

....

In the above example, BarrVer will be compiled as a literal, so [IF]
doesn't have a value to operate on at compile time. You'd need to write
this as shown below to get what you want:

: ?BARRVER ( -- n )
   [ BarrVer ] [IF] 1 [THEN]
   ( ... )
   [ BarrVer 0= ] [IF] 0 [THEN] ;
