Indexing Operator

The indexing operator takes two arguments: a set and a number (the index). The set is broken into components and the component corresponding to the specified index is returned (like a traditional array). If the index is out of range, a blank string is returned.

The first element in the set is at index zero (0).

Examples:

"Sun^Mon^Tue^Wed^Thu^Fri^Sat"[2]
Result = "Tue"

"Sun^Mon^Tue^Wed^Thu^Fri^Sat"[0]
Result = "Sun"
