Signatures of variables and constants are encoded as an index into the SymMisc heap, and a signature size. The values of the bytes are similar to those for a FieldSig (see Partition II), and include the prefix FIELD (0x6), even though the variables are not fields. Because the length of the signature is encoded in the tables, it is not included in the SymMisc heap. For example, type int32 is encoded as "0x06 0x08".
