Watch Out!!! If your program changes the last dimensioned field, you will lose the extra data!!! IIRC, the extra fields are being appended to the last dimensioned element. If you change that element, the extra fields can disappear. You'd have to do something like: MYARRAY(5)<1> = "newvalue" And not MYARRAY(5) = "newvalue"

WOW. I just found an interesting "feature" of UV. You can MATREAD a record that has more fields than are dimensioned, and you can MATWRITE that record back out INTACT without getting an error, It only bombs with an out of bounds error when you try to reference a subscript past the dimension. So....as long as any of those program dont try to mess with data it doesn't know about, we "should" be safe.
