On-rev Rename quotes work. Vars don't!

[Rick Harrison]

Hi again,

The following works:

rename "imac27.jpg" "imac2012.jpg"

what's below doesn't work:

put "imac27.jpg" into NameOfOldFile
put "imac2012.jpg" into NameOfNewFile
rename NameOfOldFile NameOfNewFile

also this doesn't work:

put "imac27.jpg" into NameOfOldFile
put "imac2012.jpg" into NameOfNewFile
put quote & NameOfOldFile & quote into NameOfOldFile
put quote & NameOfNewFile & quote into NameOfNewFile
rename NameOfOldFile NameOfNewFile

Unfortunately, I need to be able to use variables as I have
a large number of files I will be renaming, so the simple quotes
solution will not work for me.

Ideas?

Thanks,

Rick
