I FoxPro 2.5/6 whenever there was a problem in the table header with a table an error 15 - Not a database file - was generated. This would occur when you attempted to open and consequently in most cases before anything bad happened. VFP apparently does not generate this error and consequently bad things most assuredly do happen. I WANT ERROR 15 BACK!
A problem is a problem only as long as it has a possible solution. Lacking that, it becomes a FACT!
