AS 400 RPG

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.

Operating Systems

There are many computer languages, and they have been evolving from machine language into a more natural way of writing. Languages are generally classified into machine language (direct machine code); assembly (using mnemonics to present the instructions to be translated later into machine language by an assembly program); procedural languages, also known as high-level languages (HLL) (Pascal, FORTRAN, Algol, JCL, COBOL, REXX, PL/I, Basic, and C are common), along with several other types. Mainframe programming is largely done in the procedural languages.
