"The key file uses more space than it needs..."

"...should I shrink the file?".

So... if you say *no*, how does filepro know where the field boundaries
are?

It just occurred to me to wonder this, as I reduced a field length from
8 to 6, and was prompted.  I assume that the field length in the map
*does* get shorter.  So, if that's true, how does filePro know that
that field *used* to be 8 characters, so that it can calculate
correctly the field offsets?

Alternatively, if it restructures every record so that the intra-record
offsets match the new layout, where does it cache the "real" record
length (as opposed to the total of the current field lengths)?

Cheers,
