[3] [25] It was used only on IBM mainframes and had the main elements of SAS programming, such as the DATA step and the most common procedures, i.e. PROCs. [24] The following year a full version was released as SAS 72, which introduced the MERGE statement and added features for handling missing data or combining data sets. [26]
The SAS language is a fourth-generation computer programming language used for statistical analysis, created by Anthony James Barr at North Carolina State University. [ 1 ] [ 2 ] Its primary applications include data mining and machine learning .
Lattice was purchased by SAS Institute in 1987 and rebranded as SAS/C. After this, support for other platforms dwindled until compiler development ceased for all platforms except IBM mainframes. The product is still available in versions that run on other platforms, but these are cross compilers that only produce mainframe code.
PL/I (Programming Language One, pronounced / p iː ɛ l w ʌ n / and sometimes written PL/1) [1] is a procedural, imperative computer programming language initially developed by IBM. It is designed for scientific, engineering, business and system programming.
The application program interfaces of IBM's mainframe operating systems is defined as a set of assembly language "macro" instructions, that typically invoke Supervisor Call (SVC) [e.g., on z/OS] or Diagnose (DIAG) [on, e.g., z/VM] instructions to invoke operating system routines. It is possible to use operating system services from programs ...
In the early 1990s a popular solution to link PCs with the mainframes was the Irma board, an expansion card that plugged into a PC and connected to the controller through a coaxial cable. 3270 simulators for IRMA and similar adapters typically provide file transfers between the PC and the mainframe using the same protocol as the IBM 3270 PC.
Adabas, a contraction of “adaptable database system," [1] [2] is a database package that was developed by Software AG to run on IBM mainframes. It was launched in 1971 as a non-relational [3] database. As of 2019, Adabas is marketed [4] for use on a wider range of platforms, including Linux, Unix, and Windows. [5]
Hercules is a computer emulator allowing software written for IBM mainframe computers (System/370, System/390, and zSeries/System z) and for plug compatible mainframes (such as Amdahl machines) to run on other types of computer hardware, notably on low-cost personal computers. Development started in 1999 by Roger Bowler, a mainframe systems ...
