Scratch

That can be done in Panther, but I agree it would be useful to have. Though as PaperMario123 said, it would cause extreme lag over time.

And... how would it be used? Well, it could be used to create a new document in a word processor, or it could be used to make flashcards or something. I mean, you have to say the variable name, but, if it doesn't really exist until it's ran... well, you should understand. You would be able to do this in the editor. You would right click on the variable block and it would say "name my copies...". There would be another variable created called "variable1 copies", which would allow you to program the copies. Plus, it would be hard to code in Squeak. I don't know enough about Squeak to give some workaround, but I'll take your word for it . And what if someone put this in a "forever" block? Lagging to the max. I agree, it would cause lagging, but no project should need an infinite number of variables.

Also, if you were using a SmartPort system for mesh chat boxes ( a variable is created for each ip to transfer data [for my Panther projects]), you would want to be able to create/delete variables.  Maybe also a create list and delete list blocks.

Hehehe.  As for the squeak code, just ask the Panther devs.

If it was put in a c-block, it will automaticly be deleted at the end of the c-block so if put in a forever block it will be constantly be created and deleted. There would also be blocks (variable named [ ]) and |set variable named [ ] to [ ]|  so you can use theese variables. It is possible in squeak, it works in panther.

So, that solves the lagging problem.

but you can also use a list for that

How so?

add _ to _
Basically, just using the list items as variables.
However, you wouldn't be able to use this for mesh.

what you could do to solve the lag is, to have sqeuck do a counter (ctr) variable that counts how many times a variable is made using the block, and once more than ___ amount is made it stops and highlights the block red, like if you were to do:

when gf forever if <(0 / 0)>

end

Necropost...

Besides, you can use lists

One list called vars and another called vals.

when i receive [setvar v]
set [index v] to (0)
repeat (length of [vars v])
 change [index v] by (1)
 if <(item (index) of [vars v]) = (variable)>
  replace item (index) of [vals v] with (value)
  stop script
 end
end
add (variable) to [vars v]
add (value) to [vals v]

when i receive [getvar v]
set [index v] to (0)
repeat (length of [vars v])
 change [index v] by (1)
 if <(item (index) of [vars v]) = (variable)>
  set [value v] to (item (index) of [vals v])
  stop script
 end
end
add (variable) to [vars v]
add [0] to [vals v] //or any default value
set [value v] to [0]

And that's how you work around it with lists 

How many Scratchers know how to use that?  How many people use lists?  What if you need to make a variable but later replace it?   

You would just iterate through the "var" list, finding the name, and then use whatever item # it's at to replace the value in the "val" list to whatever you want.

when gf clicked
set [variable v] to [variable name]
set [value v] to [whatever value you want it to change to]
broadcast [changevar v]

when i receive [changevar v]
set [index v] to (0)
repeat (length of [vars v])
 change [index v] by (1)
 if <(item (index) of [vars v]) = (variable)> 
  replace item (index) of [vals v] with (value)
  stop script
 end
end
