Iterating loops by letter

by Apr 21, 2011

I have a need to iterate a for loop or a do loop by letter instead of number.  Is that possible?  I need to map some drive letters for users to different areas on a network.  The number of drive letters changes per user.  Sometimes it is just two drives.  Sometimes it is around eight drive letters.

For ($i=A; $i -le D; $i++){

    #Map Drive Letter using $i



I know that doesn't work but is there something like it that does?
