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) 1896 and has been used since 2003 only by S-Bahn services. This line was opened on 1 December 1898 and has been used since 2003 only by S-Bahn services. The S2 was one of the first six services of the Rhine-Main S-Bahn system. In a prior test operation it ran between Niedernhausen and Frankfurt Central Station. The service was then called R2 where the letter "R" stands for regional. In 1975 the R2 was the system's first service employing the class 420 trainset. After the opening of the Frankfurt Citytunnel the service was renamed to S2 and extended to the
