Re: Global /local variables

[Sarah]

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

Revolution... The info about declaring variables outside a handler seems to
be equal in both cases... :-(

From the �local� entry in Revolution Help system:
You can also use the local command in a script, outside any handlers in the

script. These local variables can be used by any handler in that script, without
needing to be declared in the handler itself, and their values are maintained
from handler to handler

From the �global� entry in Revolution Help system:

You can also place a global command in a script, but outside any handlers in

the script. These globals can be used by any handler in that script, without
needing to be declared in the handler itself.
