Return:
DS:SI = routine to monitor keyboard input, immediately preceded by the
ASCIZ string "WPCORP\0"

Notes: WordPerfect 5.0 will call this interrupt at start up to determine if a third party product wants to interface with it. The third party product must intercept this interrupt and return the address of a keyboard monitor routine.. Before checking for keyboard input, and after every key entered by the user, Word Perfect will call the routine whose address was provided in DS:SI with the following parameters:

Entry:
AX = key code or 0
BX = WordPerfect state flag
Exit:
AX = 0 or key code
BX = 0 or segment address of buffer with key codes.
