Calling a PC Application from RPG, Part III

Allow commands to be executed on the remote computer.

To execute commands on your PC from RPG, you must first set up a server to listen for these requests and grant permission to the IBM i to execute those commands. In order for RPG to be able to call a PC application using REXEC, you will need three capabilities:

•·         Calling the PC application from within an RPG program

•·         Allowing commands to be executed on the computer

 

In previous articles, I explained how to identify your PC on the network using the QDCRDEVD API and how to send commands to your PC using the Run Remote Command (RUNRMTCMD) command. In this article, we will install and configure a server to support RUNRMTCMD.

The current height of technology is to use the Program Error Subroutine (PSSR) to handle unexpected errors, but this article will show you an even cleaner and easier way to handle errors: the MONITOR opcode.
