Thanks! ... :-) ... I have another request: Is it possible to ask PIT (=PreIntegration Testing) to test "dbx -check access" on a regular basis, please ? This feature was broken over and over again since at least B72 and it would really be nice if it works by default in the compiler/debugger used by OS/Net (at least I really need the RTC feature urgendly to do some debugging (see http://mail.opensolaris.org/pipermail/ksh93-integration-discuss/2009-February/006919.html for a long thread about a possible memory corruption which we can't track down right now)). ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) roland.mainz at nrubsig.org \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 3992797 (;O/ \/ \O;)
