>My key generation program is also called newid(), a friend pased it to me, and I know he got it from someone else :), I've made some changes to it, among them, I took it out of the DBC procedures into it's own prg.

If you use the NewId function in the DefaultValue of the PK, you should leave the function in the DBC. That way you code it once and forget it. Otherwise you run the risk of not having the code available when adding a new record outside your application or forgetting to SET PROCEDURE to the .PRG file.

Encapsulation is a wonderful thing.
