He heard, "climb two-four thousand," hit the after-burners and was at FL 240 in no time at all, much to the surprise of the approach controller.

Anywho, the Army teaches saying "climb and maintain," and "descend and maintain" to avoid confusion. And yeah... I know it takes longer to say... using the above example it can be shortened to:

"Air Shuttle eleven-eleven, one thousand one hundred climbing eight thousand."

EDIT to add: Like Steve C said... just reread the posts and that was his example.

Not being an advocate of such language as I can see it may be a safety issue, but it is in the AIM to say FOR.
