I need to know what the previous value was in a field for processing and comparison routines. I assume I can use the TAG property to store the value before entry (using the GOTFOCUS method) and check it in before exiting (LOSTFOCUS). Is that the recommended way?

I also noticed that the TAG property is usually text... if I am storing a value, such as a dollar amount, do I need to use the STR & VAL routines to convert it or is there a way to get the TAG to be something other than text?

Thanks
