Here's a more explicit answer to the question of how to position the cursor on a PC (assuming you don't have DOS 2.00, which has been covered already). You need to assemble a routine like this, then link it with your program. I use Lattice C; if you don't, check your manual for the subroutine linkage conventions. ; curpos: move the cursor to specified location (depends on mode) ; J. J. Gillogly ; PGROUP GROUP PROG PROG SEGMENT BYTE PUBLIC 'PROG' PUBLIC CURPOS ASSUME CS:PGROUP ; ; name curpos -- set cursor location ; ; synopsis curpos(x, y) ; int x,y; x and y coordinates of destination ; ; description use video interrupt to go to (x,y) on screen ; CURPOS PROC NEAR PUSH BP ; LATTICE return conventions ; MOV AH,2 ; BIOS FUNCTION: SET CURSOR POSITION MOV BH,0 ; DISPLAY PAGE, 0 FOR GRAPHICS MODE MOV BP,SP ; LOOK FOR ARGS MOV DL,[BP+4] ; FIRST ARG INTO DL, NEW ROW (Y) MOV DH,[BP+6] ; 2ND ARG INTO DH, NEW COLUMN (X) INT INT 10H ; EXECUTE THE VIDEO INTERRUPT ; POP BP ; RESTORE LATTICE INFO RET CURPOS ENDP ; PROG ENDS END [CURPOS.ASM has been added to the Info-IBMPC library. -Ed.]
