DOS 4.0+ - DETERMINE IF CHARACTER REPRESENTS YES/NO RESPONSE

AX = 6523h
DL = character
DH = second character of double-byte character (if applicable)

Return:
CF set on error CF clear if successful AX = type 00h no 01h yes 02h neither yes nor no

Note: Supported by Novell DOS 7, though prior to Update 14, the results depended on the kernel variant rather than the YESCHAR= or COUNTRY= setting in CONFIG.SYS

BUG: Novell DOS commands and tools all use internal settings rather than this function, so the Yes/No responses are dependent on the specific country's variant being run rather than on the COUNTRY= setting
