perlquestion live4tech <p>I recently came upon the following line of code:</p> <code> $FH = $OUTFH{$name} ||= IO::File->new(">g:\\perl_scripts\\$name.log") or die $!; </code> <p>I have looked for the ||= operator and found it only in a table in perlop. There is no description of it or examples using it. I have not found it anywhere else. </p> <p>From the context of the above code line and through some testing I found that the line works like this: $FH will be set to $OUTFH{$name} if $OUTFH{$name} is defined. If $OUTFH{$name} is undefined, $FH is set to the IO::File reference.</p> <p>Is this the same as //? This is really poorly documented...</p> <p></p> <p></p>
