So tell me again who is still living in the 80's? There's several good reasons for it. Stopping or restarting from inside subroutines and canned cycles is fraught with all sorts of problems. Pausing then jogging to clear swarf or replace a tool bit and then restarting is pretty common in commercial shops, particularly when one poor guy is looking after several machines. If you making hundreds of small parts a day, it doesn't matter much if you trash one. The more expensive the part, the less likely you are to trash one and may want change tools or tips part way through. Easy and reliable without subs. One job I did springs to mind, mid way through cutting a left hand thread on the end of an expensive EN24T ground turbine shaft between centres and the insert chipped. I was running single line threading and simply paused on the rewind, stopped the spindle, jogged away replaced the insert, retouched off the tool to zero it in X, restarted the spindle and pressed run, it picked up the thread and finished it perfectly. You may understand your subroutine, but would a poorly paid operator? They can mostly understand simple code ;) There is virtually no limits to program lengths since tape died so writing subs isn't necessary to save space and serves no other purpose other than living in the 80's (or earlier :) Steve Blackmore -- ------------------------------------------------------------------------------ Flow-based real-time traffic analytics software.
