I have a geocoding program that requires me to save my spreadsheet to a db IV
file in order to import it into the program and process. The problem is
this: I have to set the column with zip codes to a required fixed width of 5
AND it must be named "ZIP". I set the width to 5 and change the header name
to 'ZIP' and then save as db IV. When I reopen it, the header name is no
longer 'ZIP' (the cell content remains 'ZIP', but the name box has changed
back to the default of 'H1'.

How do I make the changes to th the header name stay?

Thanks
