Action Flash Version: 

Pops one item and transform it into a string.

For strings, this action has no effect.

For numbers, it works as expected, it transforms them in a string (see the sprintf(3C) manual pages).

For a user defined object, the method named toString() is called.

This is similar to a Cast Object operation, although it is available in version 5 and obviously it only works for strings. It is most certainly preferable to use a Cast Object operation since version 7.
