Thanks, that makes the FOR command really easy to understand, I think i finally get it.

you can just run `SET` at a command prompt to see all the environment settings (it doesn't exactly give you an explanation, but they are self-explanatory)

if you run `FOR /? >FOR.TXT` you get a nice text file (for.txt) with the complete usage for the for command... and it explains it very well i thought
