My point is that many previous CSUBs have carried out operations that are now native commands in MMBasic. That was out of necessity at the time. I'm not saying that there is no place for CSUBs now, but that the need for them is less. I don't think this is any sort of unusual claim, just logic.
I stick by my argument that there is no place for a system that deliberately makes a MMBasic program incompatible with other versions of MMBasic or other MMBasic platforms unless that is the desired result. If you feel that you need a CSUB then perhaps your approach to the problem is wrong and that you should look for a more standard way.
Embedding machine code in a program written for an interpreter went out with the Z80 and 6502 based BASIC interpreters, which were nowhere remotely close to the speed of a modern one. There was sound reasoning for it then but it should be discouraged as much as is reasonably possible now, IMHO.
If you are using a Pico then a single PIO can execute an instruction on every clock cycle. It can do that without involving a CPU. That's infinitely faster than any embedded code you can even imagine. :)
