S (programming language) it has the common letter used in statistical computing, and is consistent with other programming languages designed from the same institution at the time (namely the C programming language). When UNIX/32V was ported to the (then new) 32-bit DEC VAX, computing on the Unix platform became feasible for S. In late 1979, S was ported from GCOS to UNIX, which would become the new primary platform. In 1980 the first version of S was distributed outside Bell Laboratories and in 1981 source versions were made available. In 1984 two books were published by the research team at Bell Laboratories: "S:
S2 (Rhine-Main S-Bahn) use the parallel running Taunus railway in this section. The Main-Lahn railway was completed on 15 October 1877 and has been used by S-Bahn services since 1978. The city tunnel is an underground, pure S-Bahn route used by almost all services (except for the S7 service which terminates at the central station). The tunnel was opened in four stages in 1978, 1983, 1990 and 1992. In a short section between Mühlberg and Offenbach-Kaiserlei the South Main railway is used. The section from Mühlberg to Offenbach Ost through the Offenbach City Tunnel was opened in 1995. This line was opened in
