Description

IndexOf returns the zero-based index of AValue in the string (Self). The value to search for can be a character or string (AValue).

if no match is found, -1 is returned.

The search can be refined by specifying a (zero based) index StartIndex. When specified, the search will start at the given character. Not specifying this option is equivalent to specifying zero.

If ACount is given, at most ACount characters in the source string will be considered for the search. This count includes the starting character. Not specifying this argument is equivalent to specifying the amount of remaining characters.
