Q. Write an assembly function which hides the cursor?

Write an assembly function which hides the cursor. Call it from a C program.

            . PUBLIC CUROFF

            . MODEL small, C

            . CODE

CUROFF PROC

MOV                        AH, 3                 ; get the current cursor position

XOR                         BX, BX             ; empty BX register

INT                           10h                     ; use int 10hto do above  

OR                            CH, 20h             ; force to OFF condition

MOV                        AH, 01               ; set the new cursor values

INT                           10h  

RET   

CUROFF ENDP

END 

The C program to test this routine is as follows:

# include < stdio.h 

void curoff(void);

void main()

 {

printf("%s\n, "The cursor is now turning off);

curoff();

 }

You can write another procedure in assembly language program to put cursor on. This can be done by replacing OR CH, 20h instruction by AND CH, 1Fh. You can call this new function from C program to put cursor on after curoff.
