; The following offsets should mimic the offsets defined
; in _FAST.H for the struct fast objects.  The only way to screw
; up these offsets would be to compile with a packing of 4 bytes,
; since all objects in the structure have sizes of 2 or 4 bytes;
; You can test for proper packing by compiling and executing
; MISC\PTEST88.C
