Tcl
This only works on Unix terminals. <lang tcl># Get how the terminal wants to do things... set videoSeq(reverse) [exec tput rev] set videoSeq(normal) [exec tput rmso] proc reverseVideo str {
global videoSeq return "$videoSeq(reverse)${str}$videoSeq(normal)"
}

set inReverse "foo" set inNormal "bar"
- Print those words
puts "[reverseVideo $inReverse] $inNormal"</lang>
