I added two new case statements, based on rexrainbow's feedback.
The Case Compare condition allows the use of a comparison operator (=, !=, <, <=, >, >=) in conjunction with a value. The Switch variable is compared to the value using the selected operator.
The Case List condition allows the entry of a list of values, each of which is compared individually. If a match is made, then the statement comes back as true. This effectively emulates an OR condition.
And yes, these various case statements make this a non-standard switch-case structure, but I am not clever enough to come up with a better structure name.
The files in the OP have been updated.
