Re: Call RPGLE program on another iSeries

John, not sure if there was a Python option available from your response or if you're just extolling the virtues of Python ? (which I also find pretty cool and easy to use.) 😉

If you do any Java programming you can use the JT400 remote command

Wouldn't Java and JT400 be a roundabout way of calling an IBM i
program from another? Wouldn't you be lengthening the call path
significantly? What value would the middleware bring to the table?

Richard has already responded, but I have my own reading of that comment:

Notice that he first includes the qualifier "if you do any Java programming". So, from where I'm sitting, at least a good chunk of the value of JT400 is that *for a certain audience*, it's going to be an easy-to-implement solution.

It's always easiest to use what you know. I often marvel at the hoops RPG programmers jump through to accomplish things that *I* find vastly easier in Python. But if you already know RPG but not Python, and especially if you have good RPG tooling and what I call "RPG infrastructure", then it may well be easier for you to write 1000 lines of RPG rather than 30 lines of Python.

I don't dispute that the "call path" may be much longer for some approaches than others. But depending on the application, that might not matter very much.
