SYNOPSIS
  COMMON [SHARED] variablelist
      o SHARED          Indicates that variables are shared with all SUB
                        or FUNCTION procedures.
      o variablelist    One or more variables to be shared:
                        variable[( )] [AS type] [, variable[( )] [AS type]]...
                        variable    A Basic variable name. Variable names can
                                    consist of up to 40 characters and must
                                    begin with a letter. Valid characters are
                                    A-Z, 0-9, and period (.).
                        type        The data type of the variable (INTEGER,
                                    LONG, SINGLE, DOUBLE, STRING, or a
                                    user-defined data type).
      o Unless it has been declared as a static array in a preceding DIM
        statement, an array variable in a COMMON statement is a dynamic array.
        Its dimensions must be set in a later DIM or REDIM statement.
