Although this is definitively worse then MSDOS menuing possibilities,

IMHO it's better then nothing. Unfortunately your MENU text gets completely
uppercase..
It's also possible to combine menu options, to avoid writing thing every
time again.
constructions like 0?devicehigh?=cdrom.sys are also possible
("if menu option 0 chosen, ask if you want to load this driver")
the selected configuration can be determined in AUTOEXEC.BAT in the
environment variable CONFIG like
if %CONFIG% == 0 echo configuration 0 selected
however, if you have no menu's in config.sys, then %config% has no value,
thus resulting in "IF == 0 echo configuration 0 selected."
(which causes syntax errors as there's nothing on the left side of == )
That's why you better use something like:
if [%config%]==[0] echo configuration 0 selected. -or-
if "%config%"=="0" echo configuration 0 selected.
then if there is no menu you have: "IF []==[0] echo configuration 0 selected."
(which will of course output nothing)
