Perl 5 version 24.4 documentation
- formline PICTURE,LIST
This is an internal function used by formats, though you may call it, too. It formats (see perlform) a list of values according to the contents of PICTURE, placing the output into the format output accumulator, $^A (or
$ACCUMULATORin English). Eventually, when a write is done, the contents of $^A are written to some filehandle. You could also read $^A and then set $^A back to
"". Note that a format typically does one formline per line of form, but the formline function itself doesn't care how many newlines are embedded in the PICTURE. This means that the
~~tokens 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.
