I might have a silly question, as first entered into script editor, there is a main tab with some script already on it. as a newbie, I would like to know what is the purpose of this default script? can it be deleted?
second question related to the new release of the new Feb QS, since I just downloaded the Nov.2018 version last week to start learning QS, now I heard a new version is up, how can I upgrade to new version? download and install over the old version or i need to uninstall the old version and install the new one? and I cannot find the correct link, the link direct me to qlikview.
