Sylvain Lauzon was saying to All on 02-24-97  00:01:
 SL> Function AL = 00
 SL> AH = 00  DOS 2.x PRINT.COM (undocumented, see note below)
 SL> 01  PRINT  (undocumented behavior also, see note below)
 SL> on return:
 SL> AL = 00  not installed, ok to install
 SL> = 01  not installed, do NOT install
 SL> = FF  installed
 SL> I installed PRINT in memory tried AH=00, it returns AL=01
 SL> " "         "     "  "      "     AH=01, it returns AL=FF
From the looks of your information, AH = 00 looks to be for DOS 2.x
only. From your results, it seems to me that you have a DOS version of
3.x or higher.
IOW, if you have DOS 2.x or lower, use AH = 00 (or it will say not to
try installing as it isn't sure what version of DOS you have, since
its newer than 2.x). I'd go with using AH = 01, though, as it seems
that it won't matter what version of DOS you have, but it will
return what seems to be the right code/message.
