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:

The section from Mühlberg to Offenbach Ost through the Offenbach City Tunnel was opened in 1995. This line was opened in 1896 and has been used since 2003 only by S-Bahn services. The S1 was one of the first six services of the Rhine-Main S-Bahn system. In a prior test operation it ran between Wiesbaden Central Station and Frankfurt Central Station.
