You still need to get the return values from registers, which is different for each swi :) But I might uneducated, maybe your way works.. ( I would say that it still need a register array pointer, setting registers to arguments, which is fine in a library function. You still need the runswi at the lowest level.

That is true. But in the end , most of riscos blocks are 4 bytes for each field.

Nah, I am the uneducated one. The problem is that right now I can't see the trees in the forest. There might be some consistent use of (amount of) return registers, the same as that there could be for input (I would have to check each and every swi call for that).
If you are able to come up with something that works for you in a consistent and uniform way (for as far as possible) then please go with that for now and not waste too much time on declaring/translating each and every swi call right now (just what you need/want for these nice examples that you are sharing with us).

I leave rtl bits to you... I can provide you with a list of swi's you need to map to the rtl functions.
About elfs and aifs .. I can run my aif with less than 1meg next slot. You need 5 for elf ( if I remember right). My window example uses 280K ram for the executable. It still allocates ram from module area.
Ehem wrong. I compared elfs with aif , they are the same. Although elf needed twice the next slot.

That's ok to leave that to me. Would be greatly appreciated if you could provide a list.
Come to think of it,the swi calls seem to be separated in different groups when browsing to the documentations so in that regards there isn't any difference with specific units that fall into a particular category (just as libraries/libraryheaders do).

I just tried my pascal generated executable converted to aif. It worked on a 8meg ram system. riscos 5.x leaves me with 1m free after boot up :)
