- Ok.. if you are using the Fossil Driver routines you can do this.
- }
-
- Procedure SetCursorPos(XPos, Ypos : Byte); Assembler;
- Asm
- SUB XPos, 1 { Subtract 1 from X Position }
- SUB YPos, 1 { Subtract 1 from Y Position }
- MOV AH, $11
- MOV DH, YPos
- MOV DL, XPos
- INT 14h
- end;
-
- { We subtracted 1 from both the X Position and Y Position because when you
- use the SetCursorPos the orgin ( upper left hand corner ) coordinates are
- 0,0. Using the GotoXY the orgin coordinates are 1,1. For example : if we
- wanted to GotoXY (40,12) using the SetCursorPos Without the subtraction
- commands the cursor would be located at (41,13). Pretty simple }
-
- { The follow Procedure gets the current cusor postion }
-
- Procedure GetCursorPos;
- { Returns then X Coordinate and Y Coordinate (almost like WhereX and WhereY).
- You must define X and Y as an Integer or Byte in the Var section of your
- Program }
- Var
- XCord,
- YCord : Byte; { Use temporary coordinates }
- begin
- Asm
- MOV AH, $12
- INT 14h
- MOV YCord, DH
- MOV XCord, DL
- ADD YCord, 1 { Add 1 to the Y Coordinate }
- end;
- X := XCord; { Set X and Y }
- Y := YCord;
- end;
