Data Manager Advance Script question

Hi all,

I would like to give user option of selecting one or more account from the list of selected accounts.

Now the following line will display whole list of accounts where as I want to only show 50 accounts where from they can select.

PROMPT(SELECT,,,"SELECT ACCOUNT","ACCOUNT")

Is it possible to maintain a file which has list of accounts and then read that file to populate accounts for selection.

Or can it be done by setting some property on Account Dim?

Please share.

Thanks,

D
