More Play with `substring()`

Play with substring() using the following applet. The parameter for substring() (in this applet) must be an integer literal like 0 or 12.

Embedded Java applet removed: modern browsers do not support Java applets. The surrounding source code is retained for historical study.

Try some strings other than the one suggested. Be sure to enclose the characters of the string with quote marks. (However, the applet does not support escape characters in the string.)
