>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.

Terry,

My startup program looks for a program named Update.fxp in the home diredtory for the system. If Update is ther it runs and erases it. I use the ALTER TABLE comamnd in the update program to make the changes along with the create view and dbsetprop.
