VMS has about 84 system services, which does not include services provided by things like the record management system. I don't have a count of system calls for TOPS-20, but I'm sure that it is more than 100. The number of system calls is not the entire story; TOPS-20 provides an overwhelming number of options on some of its system calls. Kenneth Almquist
