-- Stub file TargetRpcClientImpl.mesa was translated on 18-Feb-83 11:26:43
-- PST by Lupine of 18-Feb-83 11:25:52 PST.
-- Source interface Target came from file Target.bcd, which was created
-- on 18-Feb-83 11:26:38 PST with version stamp 361#2#12167013415 from
-- source of 8-Jul-82 9:33:34 PDT.
-- The RPC stub modules for Target are:
-- TargetRpcControl.mesa;
-- TargetRpcClientImpl.mesa;
-- TargetRpcBinderImpl.mesa;
-- TargetRpcServerImpl.mesa.
-- The parameters for this translation are:
-- Target language = Cedar;
-- Default parameter passing = VALUE;
-- Deallocate server heap arguments = TRUE;
-- Inline RpcServerImpl dispatcher stubs = TRUE;
-- Maximum number of dynamic heap NEWs = 50, MDS NEWs = 50;
-- Acceptable parameter protocols = VersionRange[1,1].
