Formal Parameters
v The formal parameters are “declared” within the
parentheses … the syntax is just like DIM statements
o As with other variables, any names can be chosen
o Each variable must be given a type: Integer, String, Double
v Formal parameter variables are “known” only within
the procedure, i.e. they are local to a procedure
o They never conflict with variables in the calling context
o Different procedures could use the same formal parameter
names without confusion or conflict
o The technical term for this is “scope”: the scope of the formal
parameter is local to the procedure.
