I need to insert an "*" into a column every 100 records.
The file contian anywhere for 10,000 to 30,000 with
columns A, B and sometimes C. I really need it to look in
column A until it is null and then insert "*" every 100
records the end of the data in column A. HELP!

are you inseting a new row every 100 records or just overwritng whats found in row 101, 201...
what's the significance of Columns B & C: you mention them but don't say why
