Event script - prohibit script execution

[AEK]

Is it possible to update a value for a GA without running the associated event script?

in script you can get value of telegram (event.getvalue()),
address of devise which send this telegram (event.dst)
and get sender (app or daemon from logicmachine) event.sender

these values could be used to stop script:
if (your condition) then return end


if your telegram is from another script you can set your own sender.
grp.sender = 'my'
grp.write.....

then yo can check like that
if (event. sender == 'my') then return end
