Return Value
Returns an array, the first element ($array[0]) contains the number of strings returned, the remaining elements ($array[1], $array[2], etc.) contain the delimited strings.
If no delimiters were found @error is set to 1, the count is 1 ($array[0]) and the full string is returned ($array[1]).

Remarks
If you use a blank string "" for the delimiters, each character will be returned as an element.
If the delimiter you wish to use is a substring instead of individual single characters, see the example below.
StringSplit is very useful as an alternative to StringInStr and as a means to populate an array.
Caution if you use the macro @CRLF you are referring to a 2 character string so you will generate extra blanks lines.
