Mass-Update
Setting this property to "1" prevents the isCOBOL framework from repainting the List-Box control each time the program modifies it. This practice is recommended to increase performance when a large number of changes are applied to the List-Box control. At the end of the process it is necessary to reset the property to its default value of "0" to see the changes.
Example - Add three items in mass update mode
procedure division. ... modify screen-1-lb-1 mass-update 1 modify screen-1-lb-1 item-to-add "item 1" modify screen-1-lb-1 item-to-add "item 2" modify screen-1-lb-1 item-to-add "item 3" modify screen-1-lb-1 mass-update 0 ... |
