   A demo in FPC Pascal using triton.library

   This is the main demo for triton.

   Updated for fpc 1.0.7.
   Added const NULL. Instead of typing longint(nil) just type null.
   After changes to tritonmacros (more overlays with SetTRTag)
   I could remove all longstr and other casts to longint.
   09 Jan 2003.
