Variable Definition Syntax

Pascal variable definition =
    host identifier... : type spec;

In Pascal, brackets ([ and ]) are part of the syntax of
variable declarations. They are also one of the
conventions used to create a syntax diagram. In the
following diagram, the expressions left bracket and right
bracket mean that brackets are literally used in the
Pascal statement. Brackets shown as ([ and ]) enclose an
optional portion of the statement.

 type spec =
    { PACKED ARRAY left bracket 1..length right bracket
    OF CHAR [ CHARACTER SET [IS] character set name] }
    | { PACKED ARRAY left bracket 1..length right bracket OF BIT }
    | BIT
    | INTEGER
    | REAL
    | { CHAR [CHARACTER SET [IS] character set name] }
