How much do you know about "set"? ------- Application Examples - China DOS Union Forum

A good header shouldn't post with documents!

You need to read the document at least eight times

Thanks, give a thumbs up. After reading this post, it can broaden my thinking. I didn't understand the application of the SET command at first, but now I understand a bit more. The more such good posts, the better.

set LgDrv=1 start 2 A: 7 C: 10 D: 13 E: 16 F: 19 G: 22 H: 25 I: 28 J:
set LgDrv=%LgDrv% 31 K: 34 L: 37 M: 40 N: 43 O: 46 P: 49 Q: 52 R: 55 S: 58
set LgDrv=%LgDrv% T: 61 U: 64 V: 67 W: 70 X: 73 Y: 76 Z: 78

This segment assigns LGDRV as the string "1 start 2 A: 7 C: 10 D: 13 E: 16 F: 19 G: 22 H: 25 I: 28 J: 31 K: 34 L: 37 M: 40 N: 43 O: 46 P: 49 Q: 52 R: 55 S: 58 T: 61 U: 64 V: 67 W: 70 X: 73 Y: 76 Z: 78"
Change this sentence to set LgDrv=1 start 2 A: 7 C: 10 D: 13 E: 16 F: 19 G: 22 H: 25 I: 28 J:
set LgDrv=%LgDrv% 31 K: 34 L: 37 M: 40 N: 43 O: 46 P: 49 Q: 52 R: 55 S: 58
set LgDrv=%LgDrv% T: 61 U: 64 V: 67 W: 70 X: 73 Y: 76 Z: 78
echo %lgdrv%
pause
Then you can see the value of variable %LGDRV%

set LgDrv=start A: Z: Y: X: W: V: U: T: S: R: Q: P: O:
set LgDrv=%LgDrv% N: M: L: K: J: I: H: G: F: E: D: C: over

This segment assigns LGDRV as the string "start A: Z: Y: X: W: V: U: T: S: R: Q: P: O: N: M: L: K: J: I: H: G: F: E: D: C: over"

Change this sentence to set LgDrv=start A: Z: Y: X: W: V: U: T: S: R: Q: P: O:
set LgDrv=%LgDrv% N: M: L: K: J: I: H: G: F: E: D: C: over
echo %lgdrv%
pause
Then you can see the value of variable %LGDRV%

Usually

set LgDrv=Z Y X  W  V  U  T  S R Q P O N M L K  I H G F E D C
or
set LgDrv=Z Y X  W  V  U  T  S R Q P O N 
set LgDrv=%LgDrv% M L K  I H G F E D C

These two kinds

This post is not good~ No follow-up~

Good post
Just makes people have to wait a long time to have follow-up

Basically, it's dedicated to batch processing

It's quite abstract?? Some parts are hard to understand

There are not many examples about set raised.

Please ask the LZ to explain the usage of SET LglDrv= in the AUTOEXEC.BAT of the WIN98 boot disk, thank you!

It would be nice to have some classic examples!

Did the original poster really understand?
After reading your article and replies,
it feels not professional enough

Mainly to discuss... But this post is also from 2006...

Are the moderators considering clearing the continuous dozens of floors of nonsense?

You go apply to be a moderator, I support you to delete posts here : )
