Get Selection while waiting to select

Example first:

User writes MOVE. Autocad asks for objects. User selects 3 objects, but hits NO Return! CMD Line still says "Select objects". He calls my lisp routine (GetNewSS) and hits return. GetNewSS is supposed to return a new selection according to what is already selected (3 objects in our case). So far everything is fine.

But I don't know how to get current selection while Selection is wanted...

I tried following and didn't work:

1) (SSGet "_I")

2) (SSGetFirst)

Both returns NIL...

I know it could easily be done if user would select objects BEFORE executing MOVE. But it is not possible.

Any suggestions will be kindly accepted. Thanks!

To explain a little more:

Write "MOVE" to Cmd and hit Return.

Select an object, but don't hit return (don't close selection).

Now write "(SSGet "_I")". It returns nil instead selected object...

Posting your code would make helping you A LOT easier.
