>>It splits the alterScope string into separate, presumably SQL command, lines using the 4 strings in new string[] as 'delimiters' For example, given:

            string alterScopeSql = "SELECT * FROM ORDERS GO SELECT * FROM Customers GO";
>>            string[] commands = alterScopeSql.Split(new string[] {"GO\r\n","GO ","GO\t","GO"}, StringSplitOptions.RemoveEmptyEntries);

then after running 'commands' would be:
>>[0] "SELECT * FROM ORDERS"
>>[1] "SELECT * FROM CUSTOMERS"
