I'm not sure if I understood this correctly or not - can I rephrase it 
and you tell me if that's what you mean, or if I got it wrong ?

Use a later version of Rev, and add a newly-added command in the card 
script. Check that works.

Then switch to an earlier version of Rev and load the stack into that; 
there should be compile errors due to the command which doesn't exist in 
this earlier version.

Yes ?  Or no ?

Is there a way to find which commands are recently added ?  Or any 
specific suggestions for commands added between 2.2.1 and 2.5 (the only 
two versions I have).

Don't think so. The handler in the card script ("Display") is called 
from the preOpenStack to fill in the field values - which it does. There 
is no other call to it except within button scripts; so the fact that it 
has values in it strongly suggests it is being successfully called from 
the preOpenStack - and it is filling in the correct values for record 
number 1. (Also checked this within debugger - and can see the local 
variable starting empty and having "1" assigned to it).

Then when I click on any of my navigation buttons, "Display" is called 
again - but the debugger shows that the local variables are all empty, 
including the one(s) set in the first time through "Display".

Moving the call to "Display" from "preOpenStack" to "openCard" SEEMS to 
fix it - but I'm worried that I'm just pushing some problem into hiding.
