9.3 SCOPE
Scope is the range within the program in which a specific definition
of an identifier exists. The scope corresponds to the part of the
program in which the identifier can be used. Figure 9-1 shows the
scope of three variables in program Modules. The scope of the
identifier A (a global variable) is the entire program. The scope of
variable B, declared in procedure Outer, is the entire procedure,
including procedure Inner. The scope of variable C is limited to
procedure Inner.
