I am often using global variables as 0/1 for booleans, or in fact for any global variable. I would like to use the other option 'text', however I'm not sure if I'm using it in the right way. e.g. if i set global variable to text and by default "used" then i want to later change it to global variable = "not used" within compare global variable, it doesn't like my text. I'm probably missing out some well known syntax here for using the text, can anyone assist?
