>>I have an XLS file (5/95 version). I am trying to import this into a DBF using the APPEND FROM ... TYPE XL5 command. It works but I get an error with Numeric Overflow - Data was lost. The XLS file can contain #NUM values in some numeric cells - the data is not important and I dont mind losing that. All the other data is imported OK. Question: is it possible to import the file without the program being halted to display this overflow error message?
