Define "fails". What happened?

Is this really the line you used? How about this instead:

out=`perl c:\\Perl\\self\\back1.pl`

Or, because I have no way to test your Windows syntax:

out=`perl c:/Perl/self/back1.pl`

Also, if Perl has been installed correctly and the Perl script is written
reasonably well, you shouldn't need the "perl" command in the line.

If these alternatives fail, you will have to run some tests, and work up to
the script.

Tests like this:

out = `perl -v`

See what this puts in the "out" variable.
