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.
