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... }
