.MODEL small, C

.CODE

CURSW PROC switch: word

MOV  AX, SWITCH                         ; get flag value

XOR  AX, AX                                  ; test zero / nonzero

:

:

   // routine to test the switch and accordingly

switch off or switch on the cursor //

:

CURSW ENDP

            END
