Notes

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
