Alternative method. If the index is [[false]], this selects the first element of the array. If it is [[true]], it selects the second one. The reason for this is that [[false]] is an alias for 0 and [[true]] an alias for 1. '''Obsolete syntax'''.  |= Example 2

When combined with the [[count]] command, this can be used to read all entries out of a config; even when you don't know exactly how many entries there will be. See the notes under [[count]] for more info.
