QAUD is an acronym for Query Add Update Delete.  I am not sure where I first heard the term or where it came from, but it relates to the common pattern you see in Informix-4gl programs.  This pattern has a MENU with the entries Query, Add, Update, Delete, and then typically First Previous Next Last Exit, in order to maintain the data in a single table.  There maybe variations in the choice of words and additional options.

With transformations from Informix-4gl to Genero you might have transformed this code to use ON ACTION and a TOOLBAR.

If you recognise this pattern, you might have it coded in many programs.  The question I raise in this article is, can this be coded smarter? i.e generically, and I believe there is something in the 4.00 Early Access Program that allows you to do this.

Read more here and join up to the Early Access Program to see if you can improve your programs that match the QAUD pattern.
