The functionality of a low-code application is stored as routines in a Rich Display file. Routines can be initiated at the start of the program, when a screen loads, or when a widget event occurs.

You can create or modify a routine in one of the following ways:

When creating or modifying a routine, a series of steps will appear:

Routines are stored at the global rather than the screen level of a Rich Display. It is possible for the same routine to be reused by multiple screens or widgets. One routine can also call another routine directly. To create a reusable routine that is not assigned to any screen event, you must assign it to the "user defined routine" property.

When you create a routine, it is given a default name. You can change the routine name in the same dialog where the steps are defined. Simply find the ‘rename routine’ icon: .  Routine names are case-sensitive and can contain spaces. The naming convention for routines is all lowercase.

You can reorder the routines on the Logic tab. The sequence of the routines does not affect the functionality of the application.
