Switches

The switches could be specified with switches command.

Some special global variables are used. $? is the index of selected switch (start from 0). $<num> indicates whether a switch is enabled, and is cleared after one switch is selected. If a specific $<num> variable is not defined or defined as null or ~, it is treated as true.

- 'Choose a switch:'
- exec: $3 = false
- switches:
  - Switch 1
  - Switch 2
  - Not enabled
- You chose switch \var{?}
