How to probe terminal dimensions from Perl

[paxxus]

As the title says. I want to probe the number of lines and number of columns in the terminal (xterm). Is this possible?

You can find the height and width in the environmental variables LINES and COLUMNS.

An alternative is to perform a TIOCGWINSZ ioctl().

Thanks john - TIOCGWINSZ also gives a lot more relevant hits in Google than what I searched for before.
