But this isn't the same thing as startup assigns, which hang around all the
time. There's nothing wrong with having PROGB (or PROGA, for that matter)
looking for an assign (set pr_WindowPtr to -1, then tru to Lock() the assigned
name) and only going to S:PROGB.CONFIG if it needs to. Also, there's nothing
very large in S:. If the disk activity bothers you copy it to RAM:.

This is the bottom line. Execute() has serious brain damage, and I hope it's
fixed in 1.4. However, there is a workaround. Have PROGB called in a workbench
environment (CreateProc, then pass a startup message). PROGB can get its
current directory from WBStartup->sm_ArgList[0].wa_Lock. The code to do this
in the general case is available from the binary groups. It's completely clean,
there's no fudges and kludges needed to do it, and you get absolute verific-
ation that the program completed (your startup message is returned). If you
like I will repost my example program.

PATHs are irelevant to the Workbench, and presumably CLI users will be
sophisticated enough to know how to do these themselves.
