The MS Copilot can convert chunks of code relatively OK - but the code only, it removes all the comments. Silly.
Where I have an issue is user interaction - using JS you lose InputBox (which I use to create primitive number-based menues) and MessageBox (where I like both the icons and the selection of buttons).
Ok, there are some workarounds, but working so-so, and only in 32-bit EA. So Sparx should suggest / create some ways of user interactions within JS scripts, beside the Session.Input and Session.Output, but I don't know, if there is enough interest.
