PC*MILERAS/400 MVS User’s Guide

 

 

 

 

7.1 Technical Overview

The PC*MILER-AS/400 system uses distributed processing techniques (i.e. the processing is split into two). The user interface or interactive software is written in RPG and runs on the AS/400. The mileage calculation software is written in C++ and runs on a PC in the Windows environment. The RPG programs communicate with the PC mileage calculation software through N/S Router or Client Access Express. The interactive software on the AS/400 allows multiple users to look up point- to-point mileages and routes for up to thirty stop-off points. The Windows server application creates a data queue on the AS/400 at startup called MIDQUE. The server application waits for mileage requests and processes them when received. The server application responds to an output queue specified within the request packet.
