Create an array containing a range of elements.
First value of the sequence.
The sequence is ended upon reaching the end value.
If a step value is given, it will be used as the increment (or decrement) between elements in the sequence. step must not equal 0 and must not exceed the specified range. If not specified, step will default to 1.
Returns an array of elements from start to end, inclusive.
Character sequence values are limited to a length of one. If a length greater than one is entered, only the first character is used.
