pathtest - mod command

There are two forms of the mod command. The first form adds a module to the list of available modules, and the second selects one of the available modules as the one to be used.

Adding a module

The command to add a card is mod +$N where the $N is the module number on the current card as selected by the card command.

Using a module

When the command "mod $N", where $N is a number, selects the Nth module. For exmaple, if no modules are open, then

mod +2
mod +4
mod 0

opens the modules in positions two and four on the current card, and selects the first of these (the module in position two) for use.

This is a command understood by the pathtest test program.
