Good communication requires that we use clear and articulate words (and phrases) that will re-create a similar thought (if not perfect clone of!) in the mind of your listener[s].

This is a totally different meaning from: CONCISE_2a: I like wearing wooden shoes which refers only to the present and is much more positive.

What you want to do isn't complicated, but it isn't simple either, unless you're familiar with VBA/VBS. I approach these problems by first getting the VBA code by recording a macro within Word. I then convert it to VB Script, which is a learning process in itself. Converting that script to Python com is another learning process and then putting the whole thing together with file finding and saving is another job. When you've done that, you won't feel able to say you're not a programmer - and you should feel familiar with Python, too. DaveM -- http://mail.python.org/mailman/listinfo/python-list
