The Combo property can be used to add an efficient and feature rich combo box drop down to an OI EDITLINE control. The user interacts with the drop down just as if it were an OI COMBOBOX control. Whenever you turn this property on, the OptionButton is set to 1 to show an option button. The option button is then used to show the drop down.
...
The LIST Format parameter is a flag allowing you to change how the data array is interpreted. Normally, the third parameter (Data) must be in ARRAY format (@TM delimited columns with @STM delimited rows). By setting this parameter to 1 however, you can pass the Data in LIST Format (@TM delimited rows and @STM delimited columns). This flags also affects the ComboDataproperty. Thus, once you choose the LIST Format, all data interaction is in LIST format.
