in reply to Exec() argument format

It could be that ComLine.pl is not executable or not on your PATH. Assuming ComLine.pl is in your current working directory, you might try: 

exec($^X, "ComLine.pl", @args);

where $^X is the name of the running perl interpreter (if ComLine.pl is not in your current working directory, use an absolute path instead).

Update: You should also add a line something like: 

die "exec failed: $!";

[download]
immediately after the exec line, because if the exec works you should not get to the next line.

    ok, thankyou

    but just for clarifictaion can you give me an example of $^X in use.

    cheers, MonkPaul.

      $^X is just a special variable, and it contains a string representing the full path to the current Perl interpreter. This is very helpful if you have more than one Perl installed.

      For example, try running the following: 

      perl -e 'print $^X'

      On the Win32 machine I'm using here at work, with ActiveState Perl, this prints:

      C:\Perl\bin\perl.exe
