redo LABEL
redo
The redo command restarts the 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 want to lie to
themselves about what was just input:
line: while (<STDIN>) {
while (s|({.*}.*){.*}|$1 |) {}
s|{.*}| |;
if (s|{.*| |) {
$front = $_;
while (<STDIN>) {
if (/}/) { # end of comment?
s|^|$front{|;
redo line;
}
}
}
print;
}
