>Couldn't these still be done by modifying the code? Data loss would only occur if I delete fields, and RI/indexing/PK loss only if I modify fields that are part of that? Couldn't I modify the appropriate code to handle this also anyway? BTW, this has now become more for my understanding of how this works than for any current practical application, but it still important for me to know (see comment below)...

Yes. As long as you use ALTER TABLE syntax. FWIW, VFP will allow you to ALTER TABLE DROP COLUMN, most other SQL databases will not.

>I have heard nothing but great things about this toolkit. I'm going to go ahead and get it. I didn't see anything at their site about a PUTM discount; think it's still available?

It is available by clicking the Product Discounts link at the top of the UT login page.
