Hi Koen.
In this partcular case I would disagree with you.
I am providing some additional functionality to an app that has already been designed.
IN this partcular App, the Record Number is irrelevant. In a partcular form, I select records into a Temporary Table, and I want to insert a row
in the middle, and then write them back out again with the inserted row in the middle. Unfortunately, the individual Rows do not have a 'Sequence number' so other than rewriting the complete app, I think that using INSERT BLANK BEFORE (Just on a temporary file) is a reasonable solution, in that Financial Considerations are important (i.e. the client will not pay for a full re-development)

Regards,
Gerard

>>1. Redesign completetrly the exisitng APP , intoduce indexes where thre were none , with a big chance of breaking it, and also investing perhaps 3 or 4 days in redeveloping and testing
