Perhaps the most well-known is Hungarian notation, which encodes either the purpose ("Apps Hungarian") or the type ("Systems Hungarian") of a variable in its name. [17] For example, the prefix "sz" for the variable szName indicates that the variable is a null-terminated string.
A nominal type system means that the language decides whether types are compatible and/or equivalent based on explicit declarations and names. A structural type system means that the language decides whether types are compatible and/or equivalent based on the definition and characteristics of the types.

Pascal stems directly from ALGOL W, while it shared some new ideas with ALGOL 68. The C language is more indirectly related to ALGOL, originally through B, BCPL, and CPL, and later through ALGOL 68 (for example in case of struct and union) and also Pascal (for example in case of enumerations, const, typedef and Booleans). Some Pascal dialects ...
Free Pascal compiler (FPC) – Free Pascal adopted the standard dialect of Borland Pascal programmers, Borland Turbo Pascal and, later, Delphi. PascalABC.NET – a new generation Pascal programming language including compiler and IDE. Borland Kylix is a compiler and IDE formerly sold by Borland, but later discontinued.
A user may define custom functions which, like variables, are identified by name rather than by a non-textual symbol. The function header defines whether a custom function is niladic (no arguments), monadic (one right argument) or dyadic (left and right arguments), the local name of the result (to the left of the ← assign arrow), and whether ...
