Am I doing this wrong.  Ok, I got my program compiled with the 
-g option, converted it to an exe file.  Tried to run it, got 
a call frame traceback on the screen then I ran:
 
symify q  /* q is the program name */
 
when I do this I usually get a shortened call frame traceback 
like:
 
C:\DJGPP\BUBBAC\QUEUE>q
one
two
three
four

               ^^^^ this is what symify puts on the screen in 
                    bright white.
 
I even tried the -o option but all it did was take the text on 
the screen and put it in a file which I named.
