Hi sunmix,
select the object with the vb-script. For example in the 1024.set the button "Ref all home". When you double click the column "value" of the line "Execute code" in the property dialog an editor is started where you can edit your vb-script. To terminate editing use the file menu. You have the following alternatives:
open files, save file as, with those options you can load data from your disk or store data to your disk.
use data and close -> the edited data is move to the screen.set file and the editor will be closed.
ignore data and close -> all new / changed data will be ignored, thus the code from the screen.set is unchanged and the editor will be closed.
