By default, when Pathagoras presents the screen on which you select one or more options, as soon as you select a second option, Pathagoras will present a series of 'connectors' from which you can pick to indicate that you want commas and the word 'and' or 'or' to automatically be inserted between the selections.



However, if you don't typically want these choices presented, you can change the default in the Pathagoras Features | All Settings |Options/Optiona' Uncheck the Display Connectors. Then if you decide you do want those options displayed for a particular varable, just add the 'connector' argument
