Anyone have a solution to that? I prefer to not } create a 'c' link Well, $$ (and all the other special variables) are special because there isn't a sensible way to implement them otherwise. In particular, $$ is the value returned from the system call getpid(). I don't think there's a sensible way to get that value apart from calling a C function. The same would apply to other variables such as $PWD. Yours, Jonathan Leffler (johnl@informix.com) #include <witticism.h>
