There's way more scenarios than doing screen rewrites when you need to know=
=20
console width. Text layout comes to mind - wrapping words at the end of a=20
line or writing a multi-column table, As a matter of fact, ignoring console=
=20
width sounds like a pretty bad thing to do when outputting any text at all=
=20
that might span over the usual lowest-common denominator of 80 columns, and=
=20
it's not completely good practice to rely on this value either, even if it'=
s=20
unlikely to ever cause problems for most programs.
