is it possible to pass AFPASSWD parameters via a script

Happy New Year All

Any idea how I can pass parameters to AFPASSWD please ? I want to change the APPS password but the method used for other utilities such as adstpall does not work.

[applmgr]$ { echo $source_apps_pwd; echo $source_system_password;}| AFPASSWD -f APPSUSER

Enter the ORACLE password of Application Object Library 'APPSUSER':
