A program associated with the control, so that in runtime the end user can activate it by performing Zoom. The variable attached to the control is sent automatically to that program.
This is commonly used when the called program is a selection program (defined with Selection Table = Yes), so it is very easy to update the control's variable with an option from a selection list.
When a program is called using the Select Program property of a variable or control, the Parallel Execution property will be ignored and the program will behave as a Modal window (Online – Since version: 2.0).
The Main Program cannot be used as a Select Program.
