Thanks Jerry,

There are major deletes (the ones I mentioned) and minor deletes 
AND about another 200 fields with values.  This is how it 
appeared in the feeble thing I use for a brain.

It only took me 4 lines to create the array with the keys I need 
in it.  The key encodes the item to delete: apply substr to it 
and I have the items to delete and the class of item they 
represent (which leads to the file name...)

I suppose I could do it the way you suggested, but then I'd need 
to get my mind wrapped around that design and this part of the 
project is 90% complete (which of course means it is 90% incomplete).

Thanks for the reasurance.
