Except for hot variables, all variables in an SPL routine are considered local unless declared with the extern or global keyword. GETVARIABLE and SETVARIABLE allow SPL routines to explicitly manipulate global variables.
GETVARIABLE also returns the value of a hot variable. See SETHOTVARIABLE to create a hot variable.
