NAME
    GoodType -- Test if a type follows the IFF 85 specification.

SYNOPSIS
    isok = GoodType (type)
     d0               d0

    LONG isok, type;

FUNCTION
    Tests the given longword type identifier to see if it meets all the
    EA IFF 85 specifications for a FORM type (requirements for a FORM
    type are more stringent than those for a simple chunk ID).  If it
    complies, GoodType() returns non-zero, otherwise 0.

INPUTS
    type    - potential 32 bit format type identifier.

RESULT
    isok    - non-zero if this is a valid type id, 0 otherwise.
