writeis done, the contents of
$^Aare written to some filehandle, but you could also read
$^Ayourself and then set
$^Aback to ``''. Note that a format typically does one
formlineper line of form, but the
formlinefunction itself doesn't care how many newlines are embedded in the PICTURE. This means that the
~~tokens will treat the entire PICTURE as a single line. You may therefore need to use multiple formlines to implement a single record format, just like the format compiler.
Be careful if you put double quotes around the picture, because an ``
@'' character may be taken to mean the beginning of an array name.
formline always returns
the perlform manpage for other examples.
