So I'm making a project where I use a piece of code that pretty much does this:

set [(variable)] to [ (join (variable) [1234] 

My problem now is that I can't UNDO this.How do I take

[ (join (variable) [1234] 

and take the 1234 back OUT of the

 (variable) 

?

I don't know if this makes sense but I need help!

P.S.: The value of

 (variable) 

is a number, not a string, if there's some sort of mathematical solution that helps.

You should be able to find what you need in here http://scratch.mit.edu/projects/18838153/

so do you want to take the 1234 out of the variable? if you do then this code might help

set [letter v] to [0 ]
repeat until <[letter] = [ 1]>
    
if <not<(letter (letter) of [variable])>> = [ 1] then
    
 change [letter v] by (1)
end
set [letter2 v] to [0 ]
repeat (letter)
    
set [variable2 v] to (join (variable2) (letter (letter2) of (variable))
change [letter2 v] by (1)
end

end

If the 1234 is definitely at the end of the variable, then this is a really easy way to do it:

set [c v] to (1)
repeat ((length of (variable)) - (4))
set [var v] to (letter (c) of (variable))
change [c v] by (1)
end
set [variable v] to (var)

@theonlygusti:

Thank you so much! After a bit of tweaking this was exactly what I needed. This took me so long!
