I'm reworking my Windows 85/86 program, and would like to know if there is any way to shrink this code:

0→x
Repeat x
getKey→x
End
If x≠[a getKey value]
Goto [label]

Is it possible? How would this be done?
It was originally TI-85 code, but it works (and preferably needs to work) from TI-82 to TI-86.

Most of my software is written on the TI-86 (with 70296 program bytes) and TI-83.
Soon a TI-82 (the third design that looks like a gray TI-89) will join my collection...

Hello Omnimaga!  
I joined a few 52 days ago and began my posting around then. I almost forgot to introduce myself!

I can't get the Casio link at the bottom of the TI wikipad to work. 

The speed difference between my TI-85 and TI-86 was 1.26:1, not the reported 2:1 from Youtube.
Device speed actually [probably] depends on several factors, such as:
ROM version
Hardware revision
Memory used
Method used to compare speeds
Battery level
Component aging
Device-to-device differences (CPU clock capacitor error [usually not too bad])
...

Therefore, the easiest way to compare speeds is to A: get several devices and compare speeds using several programs, B: replace all of the internal components with low-tolerance components, or C: get users to report their device information and time required to run a benchmark.

DJ_O: After I did the multi-device tests, I have concluded that this method was inaccurate. It's better to compare device-to-device than using a wildly-varying speed ratio.
