Compatibility: 1.0+

Expects: AH    0cH

AL    DOS input function number (01H, 06H, 07H, 08H, or 0aH)

Returns: none

Info: Clears the Standard Input type-ahead buffer then invokes the DOS

input function specified by AL.  This forces the system to wait

for a character to be typed.

These values are allowed for AL:  01H  Kybd Input

06H  Console I/O

07H  NoEcho Unfiltered Input

08H  NoEcho Input

0aH  Buffered Input

Notes:   This is normally used in cases when you want to ignore any

keystrokes in the type-ahead buffer; for instance when

prompting for an OK before formatting a disk.
