To compile a unit do this:
   gpc unit1.pas -c

The -c option tells gpc to just compile and not to link.

If you want to define a byte variable do it this way:

var
   JustAByte : __byte__ integer;

or even define a 'byte' type (This is what I do)

type
   byte = __byte__ integer;

There are many other type 'modifiers' available.  I don't have my Linux PC
with me here at work but I think the type modifier list is in the 'news'
file somewhere in the distribution.

Hope this helps!
