Chris, The programs with _DEVICEDRIVER appended to the name are directly linkedto the gplt and device driver libraries. These programs will not use a message queue with separate gplt and device driver processes. The programs are self contained as you cannot specify a different DEVICE
for output than what is part of the program. Since the programs do not use message queues, you cannot use other programs to create overlays. The advantage of these programs is generally seen when running cron jobs to produce plots automatically, when overlays are not needed. Because they do not spawn a gplt process or a device driver process, and do not use a message queue to communicate with those processes, they can avoid potential conflicts and mailbox problems if a script has problems, or a program exits prematurely.

Steve, et al, Just trying to follow this thread, but what's the difference between "gpmap" and "gpmap_gf" and "gpmap_gif"? Or the difference between "gpfront" and "gpfront_gf"? Thanks, Chris --------------------------------- Christopher McIntyre chrism@xxxxxxxxxxxx www.qwikcast.com 209.830.8028
