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