Writes a formatted record (possibly multi-line) to the specified file,
using the format associated with that file. By default the format for a
file is the one having the same name as the filehandle, but the format for
the current output channel (see the |
select() function) may be
set explicitly by assigning the name of the format to the
Top of form processing is handled automatically: if there is insufficient room on the current page for the formatted record, the page is advanced by writing a form feed, a special top-of-page format is used to format the new page header, and then the record is written. By default the top-of-page format is the name of the filehandle with
``_TOP'' appended, but it may be dynamically set to the format of your choice by assigning the name to the
$^ variable while the filehandle is selected. The number of lines remaining on
the current page is in variable
$-, which can be set to 0 to force a new page.
FILEHANDLE is unspecified, output goes to the current default output channel, which starts out as
STDOUT but may be changed by the
select operator. If the
FILEHANDLE is an
EXPR, then the expression is evaluated and the resulting string is used to look up the name of the
FILEHANDLE at run time. For more on formats, see
the perlform manpage.
Note that write is NOT the opposite of read. Unfortunately.
