Dear Rob,
I'm a very happy euphoria programmer, and I was thinking how much =
happier I would be if I could pass parameters strait to asm, and asm =
could pass params strait back. Now I know this is very similar(if not =
the same thing as c_func/c_proc/call_back) to what is available, but I'm =
a dos programmer mainly, and while I understand C and can use it well, I =
don't want to(make some kind of dos-dll system). I would very much =
apprecitive if the c_func/c_proc/call_back could be extended/combined =
with call(for asm) so I could say(do the below), I like call_back the =
way it is, but I think it should be extended to dos also(PLEASE) =
although this may require making alot of the euphoria interpreter =
reerrant(which may be more work than I relise), but the =
asm_func/asm_proc/asm_define_func/asm_define_proc should be very easy. =
Another reason for all of this is because one major things I've noticed =
is that when(In dos) I call an asm with atoms(not integer, i mean =
floating P's) the atom_to_float32/64 is very slow compared to win32's =
c_func with C_DOUBLE/C_FLOAT params, and thats probably somthing to do =
with the calling process being all builtin and not jumping back and =
forth between builtin and eu code(atom_to_float32, then poke, then call, =
then peek4, then float32_to_atom()).
I do think that a good programmer can get around the no call_back in =
dos(I have, but I wish I didn't have to) but I think the rest is way =
more needed. I hope you can see what I mean. Do keep the existing =
constructs, they have there purpose but these are more specialized for =
asm(which is all about being fast and simple, like euphoria).
Thank you very much for euphoria(I think I speak for everyone)
