Using System.in on AS/400 in a non-interactive environment

Hi All

I've written a class that validates a user profile and password
on the AS/400 for the Stalker CommuniGate Pro email server software.
It works fine on my PC but fails on the AS/400 because of
the System.in restriction. The following link talks about the
restriction:

Here is a snippet from the Stalker CG Pro docs about the helper protocol.

External Helper protocol

When the Helper program is running, the Server sends
commands to the Helper process via the process standard
input. The Server reads responses from the process standard
output.

I can't envision how to get around this.
I've tried both of these options with some test files
without any luck:

 OVRDBF     FILE(STDIN) TOFILE(TRASH/TEST)

and

ADDENVVAR  ENVVAR(os400.stdin) VALUE('/trash/test.txt')


Any thoughts or suggestions?

Thanx, PLA
