encryption and free up memory on closing

[DVGlasgow at aol.com]

2 questions, list folks.

1  I plan to store assessment records in a data stack.  Customers will pay 
for the number of assessments they  want to do.  So, in a hidden object, I 
will simply store the number they have paid for.  If they want more, I will 
send them a stack that will up the number.  The data stack will also be 
holding confidential information i don't want to be easily readable.  I was 
thinking I could set the password of the data stack, so encryptng it and 
preventing casual browsing and poking around using a text editor.  Howevere, 
i don't want my users to have to use a password. Can i just set and unset the 
password in a script as my standalone accesses and closes the data stack?  Or 
do I need to set a password and subsequently use the passkey?  How do I do 
this in a script?  The docs seem to assume that if you want to encrypt a 
stack, you also want the user to enter a password, so there are no scripted 
examples given.

2  I have set the data stack to free memory on closing.  Am i right to assume 
that this doesn't do anything in the development environment?  After closing 
I can still see the stack in the App overview and access it via same.  It 
only goes if I 'purge' using app overview or menu.

Best wishes,
