On 2000 and XP systems you can use the SET command

Thanks to Jnwei1202 for the reply. Can you give an example? @set myvar=1+1 @echo %myvar% What it outputs is 1+1.........

The set command should use the "/a" parameter, for example: set /a myvar=1+1 This parameter only works under Win2000/XP/2003 systems. The SET command is very powerful, and there are a lot of related posts on the forum.
