NAME

formline - internal function used for formats


SYNOPSIS

formline PICTURE,LIST


DESCRIPTION

This is an internal function used by formats, though you may call it, too. It formats (see the perlform manpage) a list of values according to the contents of PICTURE, placing the output into the format output accumulator, $^A (or $ACCUMULATOR in English). Eventually, when a write() is done, the contents of $^A are written to some filehandle, but you could also read $^A yourself 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 ~ and ~~ 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 TRUE. See the perlform manpage for other examples.


DISCLAIMER

We are painfully aware that these documents may contain incorrect links and misformatted HTML. Such bugs lie in the automatic translation process that automatically created the hundreds and hundreds of separate documents that you find here. Please do not report link or formatting bugs, because we cannot fix per-document problems. The only bug reports that will help us are those that supply working patches to the installhtml or pod2html programs, or to the Pod::HTML module itself, for which I and the entire Perl community will shower you with thanks and praises.

If rather than formatting bugs, you encounter substantive content errors in these documents, such as mistakes in the explanations or code, please use the perlbug utility included with the Perl distribution.
