NAME

redo - start this loop iteration over again

SYNOPSIS

redo LABEL

redo

DESCRIPTION

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 (<STDIN>) {
	while (s|({.*}.*){.*}|$1 |) {}
	s|{.*}| |;
	if (s|{.*| |) {
	    $front = $_;
	    while (<STDIN>) {
		if (/}/) {	# end of comment?
		    s|^|$front{|;
		    redo LINE;
		}
	    }
	}
	print;
    }
