isCOBOL Evolve : User Interface : Controls Reference : TAB-CONTROL : Properties : Enabled
Enabled
This property assumes a value of "0" if the Tab-Control control is disabled, "1" if it is enabled.
If either the Accordion style or the Allow-Container style is set, the following rules apply:
• When the Tab-Control is disabled, all the enabled controls inside are disabled as well.
• When the Tab-Control is enabled, all the controls inside that don't have their Enabled property set to 0 are enabled as well.
 
Example - Define a tab-control initially disabled
screen section.
