In order for the program to rebuild the indexes in database table it would also have to update the dbc file. This looks like it will work but does not seem to be the best approach. Is there a better way to delete and rebuild indexes in a database table?

David,

Think a minute. How does the index information get into the .DBC? Doesn't it get in there when you index/reindex tables? This means that they will be updated automatically.

You will need to rebuild your persistent relationships and referential integrity constraints if you delete any of the indexes which are involved.

You can run GenDBC.PRG and look at the results. But, as Ed said, you will save time and some headaches by buying SDT.
