-> Try something like this:
-> sub get_value_from_other_app {
-> my $app = '/path/to/app';
-> my $value = system( "$app" )
"system" will give the exit status of the application execution..
to get the actual output of the appln (i.e. stdout) , run the application
putting it in back-quotes..
i.e. my $value=`/path/to/app`
as for passing the output of the perl script back to the application, you can
pipe the output..
e.g. my-perl-script.pl | /path/to/app
but from your post, i did not get exactly what you are trying to do, by
accepting in a perl script a value from an application , and passing a value
back.. are you trying to write a perl subroutine to becalled from some another
application??
