11=head1 DESCRIPTION
12
13nvi with embedded perl allows you to run perl commands from within nvi.
14Two additional commands are made available when you enable the perl
15interpreter:
16
17=over 8
18
19=item * perl cmd
20
21The perl command passes the specified commands to the perl interpreter.
22The C<$VI::ScreenId>, C<$VI::StartLine> and C<$VI::StopLine> are set.
23To find out how to maniplulate the nvi screens, see L<VI>.
24
25=item * perldo cmd
26
27The perldo command runs the specified commands on each line of the range
28(every line of the file if no range specified).  Before running the
29command the line is copied into $_.  If the command returns a true value
30the line is replaced by the new value of $_.
31
32The perldo commando does B<not> set the C<VI> variables.  (If you think
33this is a bad idea, tell me.)
