Description

This command works in the same way if/else works. It is used to perform a set of commands within cases depending on conditions, which can involve attributes and/or variables.

When the first Case whose condition is satisfied is executed, it prevents the others from execution. 

The sentences specified under the Otherwise clause are executed only if all Case conditions evaluate as false.

Samples

The following code can be defined, for example, inside a GeneXus object Event or Source:

Do Case
    Case &Today.Month()=1
          &Discount=15
          &Bonus=500
    Case &Today.Month()=2
          &Discount=10
          &Bonus=300
    Otherwise
          &Discount=5
          &Bonus=0
Endcase
