function AnsiIndexStr ( const Source : string; const StringList : array of string ) : Integer;
Description
The AnsiIndexStr function checks to see if any of the strings in StringList exactly match the Source string.
When a match is found, its (0 based) index is returned. Otherwise, -1 is returned.
The string list can be specified as a square bracket delimited list, as in the example, or as an array of strings.
It is a Case sensitive command.

var
source : AnsiString;
position : Integer;
begin
source := 'Henry'; // The string to match
// Note that AnsiIndexStr is case sensitive
// We use a hard coded constant string array
position := AnsiIndexStr(source, ['BRIAN', 'JIM', 'HENRY']);
ShowMessageFmt('Index of first match attempt = %d',[position]);
// Note that arrays start at 0
position := AnsiIndexStr(source, ['Brian', 'Jim', 'Henry']);
ShowMessageFmt('Index of second match attempt = %d',[position]);
end;
