You mean: *Pointers* to procedures like implemented in gpc-2.0- don't allow
`Var' parameters.  Recent alpha versions allow both pointers to procedures
with `Var' parameters as well as BP-stype "procedural variables":

    Type
      MyProc = Procedure ( Var x: Real );
      MyProcPtr = ^Procedure ( Var x: Real );   (* `Var' parameter *)
