Aircraft X was level at FL350 and was flashing to ZLA 32 the sector the aircraft was going to be entering; ZLA32 called me and gave the control instruction; 'Aircraft X descend and maintain FL330.'  My response of 'Roger; Wilco; show it.'  I then gave the control instruction to the aircraft. The problem comes then with the fact that the aircraft was entering ZLA33's airspace with the descent clearance and ZLA32 had the hand-off; they had to show the new altitude because of the problem with the fact that ZLA does not share the idea of taking hand-offs back and entering new information rather they feel the needs to OK information into all sorts of data blocks.  The aircraft was never handed off to ZLA33 and I shipped the aircraft to the sector that it would be entering.ZLA should conform with the rest of the centers in the FAA and understand that their idea of ok functions are not needed to keep safety.  These so-called controllers in ZLA are horribly inefficient and obviously unsafe because they have all these extra procedures in place because of having so many deals; both with airspace and aircraft. There should also be directive in the .65 about who is responsible for progressing hand offs in cases like these. I am under the idea that because the ZLA controller issued the control instruction they are responsible for the progression of the hand off as well as all coordination.
ZLC Controller reports of an altitude change that he is not able to modify on the radar screen because another ATC Center has control of the aircraft.
