Re: Display shortened paragraph

I think you want "substr" (see "perldoc -f substr"):

my $maxlen = 20;  # could be 255 if you like
my $memo = "This is a really long string and I only need to show the f
+irst $maxlen characters...";

print substr( $memo, 0, $maxlen ), "\n";

Indeed his request sounds quite strange, since breaking at 255 charachters may be suboptimal for some text to be shown. However it's not entirely clear to me if he wants to read in a file by chunks of fixed lenght. If so, then curiously I wrote a note just a few minutes ago about how to use `$/` to do so. E.g.: `$/=\255;` [download]	[reply] [d/l] [select]
