Do you want to save changes to this stack ..... ?

Hi from Paris,
I have a relatively big stack (4000 cards, 6 Mb). When I run it, most
times I just do calculations on card 1 whose results are stored on this
card. In this case, from my point of view, there are no mods (although
I agree that SOME fields on card 1 have changed, but I don't want to
save the stack). Sometimes I add data cards, and so I do want to save
the stack on exit.
You can quit a stack in three ways, by (a) executing a "close stack"
command, (b) by clicking top left (Mac), or (c) by quitting Revolution.
Obviously, if I use methods (a) or (b), and answer "No" to the save
request, when I open the stack again in the SAME Revolution session,
any mods I made are there, because the stack is still in memory. If I
use methods (a) or (b) with no save, and then quit Revolution, I lose
my mods. I can go with that - it seems perfectly normal.
1 - Under what conditions does Revolution ask me the question "Do you
want to save the changes ", or more simply, what constitutes "a change"
? The answer once seemed clear to me, but maybe there are things I
don't know ! As an example, if I change the contents of a field, I get
the request to save, but if I change the labels from English to French
(by buttons), I don't get the request to save. Yet I made modifications
to the stack ! And when I execute the stack again, label modifications
have been lost. Curiouser and Curiouser !
2 - Are the conditions the same under Stack Runner ?
And the most important question :
3 - If I consider that I have made no changes, and Revolution doesn't
agree, can I bypass the "Do you want to save?" request (maybe there is
a gREV global that I can tinker with) ?
ASSUMING the answer to question (3) is YES, I want to handle the "save"
problem myself in the Stack Script :
on newCard -- I call "newCard" in a main-line script.
put 1 into IveModifiedThe Stack
if IveModifiedTheStack = 1 then save this stack -- otherwise
DON'T save !
I tried using "saveStackRequest" and not passing it, but this doesn't
appear to work, and it appears to be called AFTER the Revolution "Do
you want to save" question, thus defeating the object :
if IveModifiedTheStack 1 then exit saveStackRequest
pass saveStackRequest -- Leave Revolution to decide.
Is this the correct way to attack the problem (I hope all this is clear
to you guys) ?
