>I want to parse one feild into an undefined number of other fields named desc1, desc2, desc3... descX. I would like to address those fields from within a loop using 'desc' and appending a numeric variable that I can increment every time through the loop. Any idea what the syntax would be for that?

I'm assuming you know how you will exit the loop - but I would suggest using a FOR loop instead.

lcField = "desc" + allt(str(x))
replace (lcField) with contents
