How to put dialog in a loop in shell script and saving to file

Hi,
I am trying to input data, using dialog, into a file.
I would appreciate help on
1. how to store the input to a file?
2. how to put it in a loop to get a control on how much data is entered
3. pressing ENTER key terminates the dialog - how can I use ENTER key to function same as DOWN ARROW key

here's the code

#!/bin/bash
id=""
name=""
dob=""

exec 3>&1

VALUES=$(dialog --ok-label "Save" \
--title "Add Records" \
--form "Data Capture" \
15 50 0 \
"Identification No:" 1 1 "$id" 1 10 10 0 \
"name:" 2 1 "$name" 2 10 30 0 \
"Dob:" 3 1 "$dob" 3 10 8 0 \
2>&1 1>&3)

exec 3>&-

 

You can download ISPConfig 2 and take a look at the setup2 script. It has examples for 1 and 2 that should give you the idea.

 

thanks

thanks
points 1 and 2 are now working fine.
wonder how ENTER key can work as DOWN ARROW key in dialog form?
