Custom constants

For variables which I use universally, but which would change due to reaction to data, I use a file class called Variables, which is never saved, just held in memory. (although this is a holdover from previous versions of Omnis, where variable scopes had fewer options.)

If they are truly constant, I either declare them as task variables, or use the fields defined in the Variables class above, and populate them in a method called ‘Constants’ in my startup task.
