Scratch does not have the ability to define [[reporter]] blocks, but they can be simulated using [[variable]]s.

== Creating the Custom Block and Variable ==
<scratchblocks>
define . . . // Change . . . to the description you want. Add required parameters if needed.
. . . :: grey
set [return v] to (. . . :: grey)
</scratchblocks>

== Example ==
<scratchblocks>
// create a custom multiplication block
define Multiply (n1)(n2)
set [return v] to ((n1) * (n2))
stop [this script v]
when flag clicked
ask [What is the first number?] and wait
set [num1 v] to (answer)
ask [What is the second number?] and wait
set [num2 v] to (answer)
Multiply (num1)(num2)
say (return)
</scratchblocks>
You could also create a boolean:
<scratchblocks>
define does (n1) equal (n2)?
set [return v] to <(n1) = (n2)>
stop [this script v]
</scratchblocks>
Then you could insert it into an if statement
<scratchblocks>
if <(return) = [true]> then
Do something :: grey
end
</scratchblocks>
