Terry,

Have not done it myself, but I guess the simplest for you, unless you did some very heavy use of the .DBC, is to keep your scheme, but use the create table instruction to create the tables in the new form, while the database is open.

You could also look at Alter Table, but I get a headache when I see the Help page about it. :)

HTH,

Marc


>I periodically ship updates to my systems to the field. These updates can contain structural changes to the tables. In the past (foxpro2.6 Dos) I stored the new updated (empty) tables in an update directory. I then renamed the existing (full of data) files, copied the update table to the active directory and performed an append from to get the existing data into the new table format. VFP5 and its database (DBC) has roadblocked me from doing this.

If things have the tendency to go your way, do not worry. It won't last. Jules Renard.
