UNBOUND

 The UNBOUND attribute specifies that a routine does  not  access
 automatic  variables  outside the scope in which it is declared.
 That is, the bound procedure value of an  unbound  routine  does
 not include the static scope pointer.

 This attribute can be applied to  routines  and  formal  routine
 parameters.

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