Re: AW: "cant do that"-troubles

Hallo Till

This is a clever bit of writing using both emcsh and iosh in concert.  I 
didn't look over all of the tickle code but I believe that I'd test for 
the status of the interpreter in the file ncstart.tcl to see that it is 
idle before I allowed the processes prgladen oder starten to be called.  
Something like

if { [emc_program_status] == "idle"} {
   emc_set_wait none
   set estopstate [emc_estop]
   puts "Notaus: $estopstate"
   after 500 prgladen
   after 2500 starten
}

might take care of the error messages.

Hope this helps.

Ray
