1.1 This International Standard specifies the semantics and syntax of the computer programming language Pascal by specifying requirements for a processor and for a conforming program. Two levels ofcompliance are defined for both processors and programs. 1.2 This International Standard does not specify a) the size or complexity of a program and its data that will exceed the capacity of any specific data processing system or the capacity of a particular processor, nor the actions to be taken when the corresponding limits are exceeded; b) the minimal requirements of a data processing system that is capable of supporting an implementation of a processor for Pascal; c) the method of activating the program-block or the set of commands used to control the environment in which a Pascal program is transformed and executed; d) the mechanism by which programs written in Pascal are transformed for use by a data processing system; e) the method for reporting errors or warnings; t) the typographical representation of a program published for human reading.
