+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."
