Until now I've had the impression that global variables need to be declared,
whereas local variables do not. However, I've just noticed that (using Rev
2.7, Mac OS X) if I don't declare the local variable before the scripting, I
get an error message "Can't create a variable with that name
(explicitvariables)". This occurs whether or not explicitvariables is true or
false.
However, the Rev directions indicate that it should not be necessary to declare
local variables if exlpicitvariables is false. Is this a bug? I've also
noticed
that whereas a previously developed stack may run OK with local variables not
declared, that as soon as I make any slight change to the script the error
message appears. I recognize that it's a good idea to declare local variables
to avoid inadvertent typos in the local variables, but it would seem this need
to be addressed correctly in the directions.
