Both computers have Blackhole on.

I'm doing: Roscli -wimp office WO_RemoveTask "BlackHole2" then Roscli -wimp office Filer_Run ADFS::HD5.$.DataApps.!BlakHole2 Roscli is the command for !OscliD and WO_ is in WindOpen > then all you need is a Filer_Run command in > Blackhole's !Run file to trigger off some other program once > Blackhole has finished.

Yes: that might work. I was trying to do to much in one program I think. I can actually do a Roscli -wimp office Roscli -wimp lab Filer_Run filename which will stack in the Roscli queue and only start the second half when the first has completed. There's a funny in ShareFS about closing a file on a remote computer. This messes up Perl's open statement, so you cannot check it for success. > It occurs to me that you wouldn't need to perform a reboot either > if you could just send Blackhole a faked Wimp message with a > menu clicked reason code.

I find it impossible to remember half of whayt it can do! -- ------------------------------------------------------------------------- Richard Torrens 4QD manufacture speed controllers for battery electric motors. www sites http://www.4QD.co.uk http://www.4QDtec.com http://www.4QD.org All email addresses are copyright.
