Hi,
I'm using perl program with < write FORMAT> to generate some reports and having problems to to deal with page break and line-per-page-no.
I can't manipulate $= and $- (which are global?), no matter what I do after wanted page break (if break $- =0;) or how I set number of lines on page ($= = 33) I still have defaulted 60 lines per page and don't have wanted page breaks.
I tried to refer to them both as $= / $FORMAT_LINES_PER_PAGE, or $- / $FORMAT_LINES_LEFT ,
in fact if I let say $FORMAT_LINES_PER_PAGE =33, then $= still shows 60 . I have

Hi Trent,
I haven't used Perl's formats for ages
so I would have to reiterate over it myself again.
Maybe you find an answer in "perldoc perlform"?
Btw. as for reassigning globals,
just localize them within a code block,
would this work?
e.g.
{
local ${=}=20;
...
}
What I also remember when I worked with formats that within them you sometimes would have to use some arcane dereferencing on variables to access their value,
like
e.g.
format NAME =
FORMLIST
@{[$var1, $var2]}
.
But I my memory may misguide me here.
