If you want to learn IBM i with a modern IDE, you can actually use VS Code with https://github.com/halcyon-tech/vscode-ibmi https://github.com/halcyon-tech/vscode-ibmi. I also made a subpar guide to getting started on IBM i with RPGLE at https://barrettotte.github.io/IBMi-Book https://barrettotte.github.io/IBMi-Book. Its a really fun language/environment and I recommend anyone take a try at coding something trivial.
