"waitfile" waits for a specified file without sucking the guts out of
your CPU since checks are made in every one tenth of a second intervals.

It is currently believed that using "waitfile" in your DOS script
is superior to doing it entirely with the DOS script.

So "waitfile" would replace the following:-

lab top
if exists $prefix:home/$user/Public/tmp/ffp.tmp
   set sz `c:list $prefix:home/$user/Public/tmp/ffp.tmp LFORMAT "%L"`
   if val $sz not GT 0
      c:wait 1
      skip back top
   endif
else
   c:wait 1
   skip back top
endif

with:-

c:waitfile $prefix:home/$user/Public/tmp/ffp.tmp

.

Of coarse "waitfile" can be aborted with a Ctrl-c if your file
decides to not show up.

"waitfile" has been tested on 68k and on the native sides of WinUAE
and AmiBerry when waiting for redirection files.

NB:  Zero byte files do not count.
