The $= variable holds the number of lines allowed on a page.
|
|
When the line number exceeds this amount, write outputs a new page.
|
|
$= defaults to 60.
|
|
The $- variable counts down as each line gets output on a page.
|
|
When $- gets to 0, write outputs a new page.
|
|
You can set $- to 0 to force a page output on the next call to write.
|
|
Setting $- works only if you have a top-of-page format, e.g., FILEHANDLE_TOP.
|
