String.Slice Method

Explanation	Cut out a part of the character string. This method cuts out the character string without being aware of the character type of the target character string. Use the mid function to cut out a character string that contains double - byte characters in the target character string. The difference with Substring method When length is the length of a character string, if a negative value is specified for start, it will be processed as length + start. If a negative value is specified for end, it will be processed as length + end.
Call format	var s = str.Slice( start [, end ] )
Return value	Cut out character string
Arguments	integer start	Leading position to cut out Specify a number starting from 0.
	integer end	End position to cut out (cut out to the character before the specified position) Specify a number starting from 0 . If omitted, it will be cut out to the end of the character string.
Exception	Func-4	Invalid argument
Example of use	`var str1 = new String("abcdefg"); print(str1.Slice(2, 4), "\n"); /* If the target character string contains double-byte characters */ var str2 = new String("東京都千代田区千代田1番1号"); print(mid(str2, 3, 4), "\n");`
