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.
