Form
REN <filespec><filename>
Description
1. The first option (filespec) must be given a drive
designation if the disk is in any other drive than A.
Any drive designation for the second option (filename)
is ignored. The file will remain on the disk where it
resides.
2. The wild card characters may be used in either
option. All files matching the first filespec are
renamed. If wild card characters appear in the second
filename, corresponding character positions will not be
changed.See example 2.
An attempt to rename a filespec to a name already
present in the directory will result in the error
message "File not found".
