applescript/setting context

[steven....@gmail.com]

I have a simple applescript that I use when excavating my inbox -- if
I'm looking at an email that I should respond to "sometime soon", I
use this script to create a new task for me in EasyTask...

This would be even more useful if the script could set the Context
value, so I could easily locate these tasks when I have a bit of time
to catch up on email....

is there some way to set this value, via applescript?

Thanks!
