DEFINITION MODULE Editor ;

(* WordStar-style full-screen editor for the TP3 project.
   Operates directly on TextBuf (the shared TP3 text buffer).
   Returns to the menu on Ctrl-K-D; leaves the text in memory
   and reports whether any editing happened via "changed". *)

PROCEDURE Run (drive : CHAR ; VAR fileName : ARRAY OF CHAR ;
               VAR changed : BOOLEAN) ;

PROCEDURE GotoOffset (off : CARDINAL) ;
(* Arm an error jump: the next Run places the cursor on the given
   0-based TextBuf offset (TP3 errexit + editor2 path used by CmdCompile).
   The view scrolls to follow; ignored if no Run follows. *)

END Editor.
