If your book says this, then it's wrong on 2 counts, both of which you
seem to have discovered yourself:
1) command-line parameters are passed through the @ARGV array, as
documented in perldoc perlvar, and
2) shift will shift @_ in a function, and @ARGV in global scopes, rather
than always working on @_. See perldoc -f shift for more detail.

Unless you actually plan to keep more than one argument in
@firstCommandLineArg, perhaps you should use a scalar, like
$firstCommandLineArg.
