| 'Absolute movement |
| DRAW "M 50,80" |
| DRAW "M 80,50" |
| 'Relative movement |
| DRAW "M+40,-20" |
| DRAW "M-40,-20" |
| DRAW "M-40,+20" |
| DRAW "M+40,+20" |
| 'Using a string variable. |
| X$ = "400" : Y$ = "190" |
| DRAW "M" + X$ + "," + Y$ |
| 'Using numeric variables (note the two "=" signs). |
| A = 300 : B = 120 |
| DRAW "M="+VARPTR$(A)+",="+VARPTR$(B) |
| |
