Hi there Is there a way to implement with minimal system strain, a wait proc. Basically something similar to tcl after command. I need to do some work every say 30 secs. I wonder if there is something I can use like while 1: myproc() wait(30) Thanks sreekant -- A man needs to sleep for 36 hours a day atleast. Sent via Deja.com http://www.deja.com/ Before you buy.
