There is a script file in the Mailers+4 directory named "AddressPresort.txt". This script will only...
1. Open the file
2. Run address check and print the Cass Form
3. Run Presort and print the Qualification Report, Presort Parameters and the Postage Statement.
Mailers+4 cannot be used in conjunction with any other languages. The scripting options are limited and the only functions available are what I described above. We do have a presort object where you can customize a presort program. Below is a link with more information on the presort object. It supports Standard and First Class mail.
