How to solve this: change ALL the elevations ...

Does anybody know how to do this:

Change ALL the elevations in the drawing by adding 153m. That is, if the text shows an elevation of -0.352 you need to add 153 to this so that it will say 152.648. You can add 153m to each elevation one at a time... but this would take an enormous amount of time. It would be much easier to load up the lisp routine that I provided and change the elevations all at once.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The easiest way to do that is to run the following commands:
move (hit enter)
all (enter)
0, 0, 0 (enter)
0, 0, 153 (enter)

this will move all objects in the drawing only in elevation. If you need more info about how to do this just let me know and ill provide some screen shots

If you can give me more details that would be great!
Make sure to select the Model tab within AutoCAD to get into the active drawing, then in the AutoCAD Command Window keyin:
MOVE (press enter key)
It will then ask for "Select objects:", so keyin:
ALL (press enter)
hit the enter key again to accept all the selected items, then once it asks "Specify base point or [Displacement] <Displacement>:" keyin:
0,0,0 (enter)
it will then ask for "Specify second point or <use first point as displacement>:" then keyin:
0,0,153 (enter)

you have now moved all items within the drawing only in elevation
