(delay 1 (set pc something))

was already implemented and working for SIM (fr30 uses it). It appears that

(set (delay 1 pc) something)

was only implemtned for SID. Furthermore, SIM now only accepts the 
former and SID only accepts the latter, making it difficult 
(impossible?) to share a .cpu file for both back ends.
