Compatibility: 1.0+ Expects: AH 0bH ────────────────────────────────────────────────────────────────── Returns: AL 0ffH if a character is available from the Standard Input 0 if no character is available ────────────────────────────────────────────────────────────────── Info: Checks the status of the Standard Input. If Ctrl-Break is detected, INT 23H is executed. Notes: ■ Use before Fns 01H, 07H, and 08H to avoid having DOS wait for a key. ■ This is a simple, non-destructive way to check for Ctrl-Break during long calculations or other processing that does not normally look for input. It lets the user abort from such a sequence. See Also: INT 16H Character I/O Functions DOS Functions -♦-
