y have writen the following code

Library Fgw32.DLL

AS Lineto 2 CImport: fg_Draw
AS Moveto 2 Cimport: fg_move

after y have writen in my definition

40 100 moveto \ = access violation
120 120 lineto \ this command have generated an access violation

PS.

I have writen an complet graphic library under DOS with fastgraph for DOS
and TF83

I will transfert it to SwiftForth. For this I needed technical support
because I have not enough knowledge for window programming.
An other difficulty for my is that my english vocabulary is verry verry smal.
Following you can see an exemple of code with Tf83 + Fastgraph.
It can draw an line from an mousecliq to an other mousecliq
It is verry simplicity
Later you can have free use of my source code when you have interest.

: SETLINE ( --- ) \ Line drawing

   0 639 0 479 Setclip \ limit of clipping in the visible window
   GetMouseCliq moveto
   GetMouseCliq lineto
   XXCLIP 2@ YYclip 2@ SetClip
