3.2.120 redo

redo LABEL
redo

The redo command restarts a loop block without evaluating the conditional again. The continue block, if any, is not executed. If the LABEL is omitted, the command refers to the innermost enclosing loop. This command is normally used by programs that wish to deceive themselves about what was just input:

# A loop that joins lines continued with a backslash.
LINE: while (<STDIN>) {
    if (s/\\\n$// and $nextline = <STDIN>) {
        $_ .= $nextline;
        redo LINE;
    }
    print;  # or whatever...
}
