Runtime Compatibility Mode property

Specifies the Form Builder version with which the current form's runtime behavior is compatible (either 4.5 or 5.0 +). By default, new forms created with Form Builder 5.0 and later are set to 5.0-compatible. Existing forms that are upgraded from 4.5 are 4.5-compatible. To get these forms to use the new runtime behavior of 5.0 +, set this property to 5.0. The runtime behavior that is affected by this property is primarily validation and initialization.
