$ACCUMULATOR

$^A

The current value of the write() accumulator for format() lines. A format contains formline() commands that put their result into $^A. After calling its format, write() prints out the contents of $^A and empties. So you never actually see the contents of $^A unless you call formline() yourself and then look at it. See the perlform manpage and formline().
