Ah, I see you used "&&" whereas I just used a semicolon separator. wonder if it would make any difference.... (I understand that the "&&" causes the second command to be skipped if the first one fails, while the semicolon keeps it as two independent commands.) I don't expect to be back there til Monday, but I'll try some of these variants when I get there. (I could VPN in and try it, but if something goes haywire, then I'm scrod for remote access.) -- ---- Fred Smith -- fredex at fcshome.stoneham.ma.us ----------------------------- The Lord is like a strong tower.
