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 https://4js.com/ask-reuben/ig-86/ and join up to the Early Access Program https://4js.com/download/eap/? to see if you can improve your programs that match the QAUD pattern.
