Here is a routine which should work.

If you have problems, let me know.
(Sometimes code I extract from larger projects only works because of other plugins I have loaded already)

Place Win32API.so in the Plugins folder (I grabbed a copy from the ruby install and placed it there)

place clear_ruby_console.rb in your Plugins folder.

"Clear Ruby Console" should appear at the bottom of the Window drop-down menu after you start SketchUp

clear_ruby_console.rb

Thanks, it works! And I learned something new (win32api calls) with this example of yours. Thanks!
Yet, be careful there... I am sure you know about this but, in ruby only "false" and "nil" evaluate to "false", "C language" NULL does not, so you need to test against 0(zero) instead of using the "not operator" on the return values, which are numbers and therefore using "not" always yield to false in ruby.
