Well, you're both right.  I think how works is this, it compiles the code
when you load the program.  So, with turbo, you get fast load, slow compile,
and the other way around with Mystic.  Have this guy give times for:

START
C> turbo sample.pas
   C (i think you type C for compile)
   [line #'s flashing by]
   Done.
STOP

START
C> mystic sample.pas
   C (or whatever)
   Done.
STOP

I think you'll find them comparable.
