redo
redo - start this loop iteration over again
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:
# a simpleminded Pascal comment stripper
# (warning: assumes no { or } in strings)
LINE: while () {
while (s|({.*}.*){.*}|$1 |) {}
s|{.*}| |;
if (s|{.*| |) {
$front = $_;
while () {
if (/}/) { # end of comment?
s|^|$front{|;
redo LINE;
}
}
}
print;
}
