Hi,
Suppose I run an application from within a perl script, with system (eg
system ("myfavprogram input_file out_file")).
Is there a way to let the script know that the program has finished running
and that I can move on to the next step in the perl script?
TIA,

I usually do not use system or command ticks.
I always pipe the output to STDOUT if I wish to manipulate the output of
any system
command. Alternatively, you could redirect output to a TEMP file, then
read from that file,
but "piping" is more efficient.
open MY_STDOUT, "{system command} | "
