Global /local variables

Imagine you have a button, and in it's script you have several 
handlers: mouseUp, processData, doMoreStuff etc. If you put a local 
variable in the button's script but OUTSIDE any of the handlers - say 
on the first line - then all of these handlers can access the data 
stored in that variable. However no other scripts e.g. card script, 
stack script, another button's script - can access that variable. If 
they declare a local variable even using the same variable name, it 
will refer to a new variable.

If instead of "local", you declared that variable as "global", then any 
handler in any script could access it, either by declaring it inside 
the handler or in the script but outside the handler.

Cheers,
Sarah
