Automatic and Static Variables
 
BASIC procedures can use both automatic and static variables.
 
  ■ Automatic variables are initialized at the start of each call to the
    FUNCTION or SUB.
 
  ■ Static variables retain values between calls.
 
You can control whether the default is automatic or static by using or
omitting the STATIC keyword in the SUB or FUNCTION statement.
 
  ■ If you omit STATIC, then the default for variables is automatic.
 
  ■ When you use STATIC, the default for all variables in the procedure is
    static: the values of the variables are saved between procedure calls.
 
You can make selected variables in a procedure STATIC by making the default
automatic (omitting STATIC from the SUB or FUNCTION statement) and using
the STATIC statement.
