Apple mentions in Inside Mac 1 that there is no way the Lisa Pascal
compiler can call a routine pointed to by a ProcPtr.  Probably the
same problem exists with LightSpeed Pascal.  Does anybody know a way
around this with INLINEs?
   Apart from that, your translation of C to Pascal is incorrect.
The C statement "if (rsrcH = GetResource('code',2000)" includes an
assignment, NOT a equality comparison.  This should be translated
as:
       rsrcH := GetResource('code',2000);
       if rsrcH <> nil then ....
