%TYPE is modeled after the OpenVMS DCL lexical function
    F$TYPE. %TYPE is used to obtain information about a name. The
    value returned is a numeric value with certain bit positions,
    either 0 or 1, depending on whether the specified name has the
    corresponding attribute. As described elsewhere, the decimal
    digits of the numeric value are substituted for the %TYPE lexical
    operator. %TYPE Attributes shows the symbolic names that are
    predefined for each attribute.
