RN.COM (v2.1) is a wildcard file rename utility that allows you  
to rename groups of related files.  If the new name already 
exists, you will be asked if you wish to replace it.  As of V2.0, 
RN supports ZCPR drive/user syntax (a13: b: 11: a*: *: [=alluser] 
and the intuitive oldfile=newfile order used in MS-DOS.  V2.1 is 
reentrant. 

Format:  rn  [du:]oldfile=newfile (*,?  OK) 

The new name cannot be more ambiguous than the old.  

Examples:  rn  1:blurk.*=zap.* renames all blurk.* files to zap.* 
in user 1 of current drive (blurk.qqq  >  zap.qqq) 
rn  c12:z*.*=x*.* makes all filenames on C12:  starting with  "Z" 
begin with "X" 
rn zap.*=*.qqq is illegal

To exit, type a CR at the ">>" prompt.
