Variable Declaration
A variable can be declared as local to one program unit or common to two
or more program units. A local variable can be accessed only by the
program unit in which it is declared, whereas a common variable can be
accessed by every program unit that declares it.
A local variable can be declared explicitly by a variable declaration
statement, or implicitly the first time it is used. A common variable
must be explicitly declared with the COM statement in every program unit
that uses it.
Table 3-9 lists the variable declaration statements and the
characteristics of the variables that they can declare.
