I am currently using StartApp to launch an external program; however, I need to wait for that external program to finish its job before my LISP routine continues. I know it would be possible to use DOSLib to do this; however, I would like to avoid dependence on a third party if I can, does anyone have some ideas?
I could potentially loop until a file is created; however, there is the very real possibility that the file won't get created all of the time and would end up in an endless loop, so I would like something with a bit more of a failsafe.
