Eng:Length of () (Operators block)

The Length of  block is an Operators block and a Reporter block. The block reports how many characters the given string contains.

Example Uses
In certain projects, different events can happen based on the length of a value; this block is used to help.

Some common uses for the Length of block:
 * Checking the length of a name

ask [What's your name?] and wait say (join (answer) (length of (answer))) for (2) secs


 * Checking how many digits there are in a player's score

forever say (length of (score1))


 * Chatbots, where different messages can occur depending on the length of the message that was inputted

if <(length of (answer)) < (10)> then say [Hi!] else say [Bye!] end

Workaround
This block can be replicated with the following code:

set [length v] to [1] repeat until <(letter ((length) + (1)) of (thing)) = []> change [length v] by (1) end

It can be flawed because it can be long and slow. This is also a problem:

set [repcount v] to (0) repeat until <(letter ((repcount) + (1)) of (string)) = []> add (letter ((repcount) + (1)) of (string)) to [results v] change [repcount v] by (1) end set [length v] to (length of [results v])

It takes up lots of memory and can be slow. However, both values can be saved for later.
