    Yes - the 'qx' and backticks provide that functionality. The perl script waits for the command to complete, then executes the next perl command. 
    use strict;
use warnings;

my $externalExe="C:/path/to/myprog.exe";

print "Starting external program...\n";

print for qx|$externalExe 2>&1|; # Executes the program, and prints it
+'s output 

print "Program $externalExe run completed.\n";

    If you want to execute a .bat under Windows, then you need to have a script file that Windows understands.

    I suggest that you type: "help start"
    to see the options for that to make a more complex Windows .bat file.

    To capture the output of a shell command (Windows or not) in Perl in the most simple way, use "backticks". 

    #!/usr/bin/perl -w
use strict;

my $result1 = `dir`;
print $result1;

my $result2 = `dir *.txt`;
print $result2;
