LOCAL VARIABLES: The VMX300(-E) scripting language has local Boolean variables that are declared in a script’s DIM or VAR statement. They are
local in the sense that they can be accessed only within the script that declares them, as well as from any global script the script calls using the
CALL command. They cannot be accessed from a global script run using the RUN command. Any script, global or local, can declare local variables.
