I haven't used FastGraph, but you made me curious enough to look
at the on-line documentation. There, it says, "Fastgraph for Windows
uses the same naming and stack-based calling conventions used by the
Windows API functions." Section 8.2 of the SwiftForth Reference Manual
says that Pascal prototype functions are standard in the Windows API.
Have you tried:

  AS Lineto 2 Import: fg_Draw
  AS Moveto 2 Import: fg_move

None of your code examples shows any initialization calls to FastGraph.
Likely it needs these to allocate memory for its frame buffers. =
Generating
an exception seems like a sure bet if draw to memory that hasn't yet=20
been assigned to FastGraph with something like fg_vbinit().
