Why test another function (which is really undocumented at that, so
unlikely to be implemented properly in other DOS versions) to determine
whether function 7303h is sup

That is
Frank van Gilluwe produced a very similar book called "Undocumented PC;" it is
based heavily on Ralf Brown's work. The 2nd edition came out in 1997, but still
doesn't go much beyond DOS 5. This book comes with a 3 1/2" floppy containing
several code fragments that might be of interest to someone

to me it looks like you are either
a) a complete idiot that is not able to ask google about
'int 21h function 7303h'
b) a huge troll
in both cases please

NO, see above.
