In scratch, if you make a block, it can use arguments, but it cannot return a value.
Example:
I thin this would be a very useful feature because although there are ways to do this, it requires more blocks

set [name] to [generate_name()]

I'm sorry, but I don't understand. Could you please explain?

If you support, it should be +1. If you don't, it should be +0, not -1. If you half-support, it should be +1/2 or +0.5, not +0. You can't subtract from the supporters.

What I mean is, when you make a block, it can return a variable that can be set inside the define block I'm sorry, but I don't understand. Could you please explain?
Here is a link I found about functions
It's the alternative of doing this:
define RandomBlock
set (return value::motion) to (pick random (1) to (10))
when green flag clicked
RandomBlock
set (x::motion) to (return value::motion)
because instead you could do this:
define RandomBlock
return (pick random (1) to (10))
when green flag clicked
set (x::motion) to ({RandomBlock :: looks})

This already suggests custom reporters and booleans.
define(function(arg1 :: custom-arg) (arg2 :: custom-arg) :: custom) :: custom hat
::custom cstart
...
{return (... :: grey) :: custom cap} :: custom cend cap

Has already been suggested … a lot.
The ST have already pretty much implemented this anyways.

Pretty sure they haven't. Please explain. Has already been suggested … a lot.

Oh yeah, I'd also like to add that “has already been suggested” means that you should go over there and add your support, not that you should let the issue drop.

As a long time Scratcher, I have found new meaning to the name “Scratch”: for me, it means to “scratch that itch”, to come back again and again to realize new ideas in this toy language, even when I'm capable of creating my projects in real programming languages years later. It's a friend that helped me to pursue programming and get me to enjoy its fruit. I'm certain many others who have walked this path as well have grown fond of its importance in their life.

How has the ST implemented this? Where? If it has, I support the ST making it a lot more accessible. Has already been suggested … a lot.

I strongly support this and not just because it would help Scratch programming. IMHO the best argument is that value returning functions are central to both programming and more generally mathematics. Without it, Scratch is not allowing what's certainly a central idea of all algorithmic systems to be explored.
A possible way to do this might be to just have a simple “return” control block, i.e.
A possible way to do this might be to just have a simple “return” control block, i.e.
return [ ]It would both set the value of the block for the calling block and act as a “stop” for the custom block. It could also be used for a non-value returning block to terminate, the value wouldn't be needed in this case. This also has the advantage of looking like most other programming languages.
define Raise (base) to (exp)
if <<(base) < [0]> and <<(exp) mod [0]> > [0]>> then
return[] // imaginary
end
if <<(base) < [0]> and (((exp) mod [2]) = [1])> then // odd power of negative number
return(([e^ v] of (([ln v] of ([abs v] of (base))) * (exp))) * [-1])
else // even power of any number
return([e^ v] of (([ln v] of ([abs v] of (base))) * (exp)))
end

To use the above:
or maybe this would be clearer:
set [value v] to (Raise [-2] to (power))
or maybe this would be clearer:
set [value v] to (call (Raise [-2] to (power)))

And I STILL want to know where this has been implemented, if it apparently has.

I believe this is working on being implemented. I saw a ST member post it on something. Bump
