If you know how to make a simple proof of concept I’d be curious to test it. I remember when I was talking about coroutines some time back I found this (http://www.festra.com/wwwboard/messages/12775.html) which does some stack pushing/popping or stack variables.

As an side, does the inline assembly in FPC work on arm64 or is it Intel only?
