Default \ Standard Variables

[BatchRocks]

Does anyone know default Variables, unlike..

Set cow = ff
echo %cow%

I only know OS, HomeDrive, HomePath, CD, and Random. Thanks...

what do you mean "default variables" are you talking about variable data-types then:

• Batch doesnt have user specified data-types, they are variant

or are you asking about other enviroment variables like: %SYSTEMROOT%?

Please explain more fully

Yes, variables like SYSTEMROOT and things like that.

Typed SET at the Command Prompt?

There's a list I got when I typed set. It showed me all the system variables. You might not have all these variables.

You're freaky...*Stares suspicously*

Thanks! Lols.

[BatchFileCommand]

Not like I memorized all of those  .

[macdad-]

learned something new: USERNAME
this will be more helpful in my next batch program.

[BatchFileCommand]

%homepath% or %homeprofile% are very useful. They give the paths to the user profile.

[GuruGary]

There are some that don't show up in the SET command, like the dynamic variables and a few others including:

%cd%
%date%
%time%
%random%
%cmdcmdline%
%cmdextversion%
%errorlevel%
%=exitcode%

[BatchRocks]

Thanks Gary, I knew about Errorlevel, but it just slipped my mind :O!

Isn't it:

Code: [Select]

set random=%%9
?

Code: [Select]

set /a number=(%random% %% N) + 1
will give a randum number between 1 and N inclusive

No. A good motto: Research first, then post.
