Q . Write a subroutine in C which toggles the cursor?

Write a subroutine in C which toggles the cursor. It takes one argument which toggles the value between on (1) and off (0) using simplified directives:

PUBLIC CURSW

.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

In a similar manner variables can be passed in C as pointers also. Values can be returned to C either by altering the variable values in C data segment or by returning the value in registers as given previously.
