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

Main article: List of Block Workarounds

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.
