C can pass by reference, no? think about it: i pass by value when i pipe into a program, and i pass by reference when i tell that same program which file to read. standard unix filter procedure. when passed as a pipe, the original data can't be modified. when passed as a file name, the data can be modified *and* there is nothing copied (ignoring what the program does)... -- martin; (greetings from the heart of the sun.) \____ echo mailto: !#^."<*>"|tr "<*> mailto:"; net@madduck stay the patient course. of little worth is your ire. the network is down.
