Though in A68 this was a shorthand for > ref = loc I don't know if it was purposeful or not, but Algol 68 had the notion of deproceduring - i.e. function call, which seems to have carried over into C where the name of function is a pointer to it. You can do void myproc(); void (*functptr) = myproc; ... funcptr() to call through the pointer. (Even though the K&R book taught us to use (*funcptr)(), the syntax above worked at least as far back as PCC.) Did C pick this up from Algol 68? I have no idea, but it would not surprise me if it had. Arnold
