The AUTOEXEC.BAT in the WINDWOS 98/ME boot disk has 2 lines:

set LglDrv=27 * 26 Z 25 Y 24 X 23 W 22 V 21 U 20 T 19 S 18 R 17 Q 16 P 15

　　set LglDrv=%LglDrv% O 14 N 13 M 12 L 11 K 10 J 9 I 8 H 7 G 6 F 5 E 4 D 3 C

What is the meaning, principle and usage of this?
Thanks

This is for this line of service:
call setramd.bat %LglDrv%

set LglDrv=27 * 26 Z 25 Y 24 X 23 W 22 V 21 U 20 T 19 S 18 R 17 Q 16 P 15
set LglDrv=%LglDrv% O 14 N 13 M 12 L 11 K 10 J 9 I 8 H 7 G 6 F 5 E 4 D 3 C

It is to set the %LglDrv% memory variable.
One line is up to 127 characters, so two lines are typed.
Confirm the available drive letters at the front for the memory drive to use.

Thanks.
So, how is this confirmation action done? CALL SETRAMD.BAT %LglDrv% is in the back. The.Llgldrv variable is assigned values from 27 to 3 in turn. I think there should be an IF statement or something that keeps looping.

When booting, press SHIFT+F8 (step-by-step boot) for debugging, and you will be able to see the specific steps.

What does the value of the LglDrv variable, which is a long string, mean? Please have an expert explain it.

Oh my god, the thread starter doesn't even understand such a simple batch processing. Speechless....
