That has the same cost + overhead as the current scheme, which is just that wrapper in C. 3) Inspect the delegated method or MMD sub and save only the needed register range. E.g. if a MMD sub doesn't use I and N registers, only S[0]..P[31] needs saving. That reduces memcpy cost by 3/5. Doesn't work, when the sub calls another sub of course. But for simple functions it'll work. leo
