BYTE

 The BYTE attribute specifies the amount of storage in  bytes  to
 be received by the object.

 Syntax:

    BYTE [[( n )]]

 The optional constant 'n' indicates the number of  byte  storage
 units.  It must denote a positive integer.  If you omit 'n', the
 default value is 1.

 See the "HP Pascal Language Reference Manual" for  the  complete
 description of using the BYTE attribute.
