Ok, I know an awful lot more about .dll files than i used to! I managed to compile foo1.c and recompile choice.c although I could not use the makefiles provided, in the end I just compiled them from VC++ running in windows, now I guess all i have to do is study the code! Thanks for all the help, oh yeah the confusion as to the -nogui was that i thought it would give you a similar environment to csound whereas one can load + change score files from prompt('-L stdin').
regards, Rory.
