"Oil Can 123, cross XYZ at 9,000 climb and maintain 12,000". Years ago controllers used to issue this and it created a lot of confusion and my understanding was that they were going stop wording the climb clearance this way. A few days ago I heard it again worded like that.
Many pilots were thinking it meant cross XYZ at or above 9,000 and climb and maintain 12,000. In fact the controller wanted the pilot to stop at 9,000 until XYZ, then climb to 12,000.
