This document specifies the form and meaning of programs written in Ada. Its purpose is to promote the portability of Ada programs to a variety of computing systems.
This document specifies:
— The form of a program written in Ada;
— The effect of translating and executing such a program;
— The manner in which program units can be combined to form Ada programs;
— The language-defined library units that a conforming implementation is required to supply;
— The permissible variations in conformance to the rules of this document, and the manner in which they are to be documented;
— Those violations of the requirements of this document that a conforming implementation is required to detect, and the effect of attempting to translate or execute a program containing such violations;
— Those violations of the requirements of this document that a conforming implementation is not required to detect.
This document does not specify:
— The means whereby a program written in Ada is transformed into object code executable by a processor;
— The means whereby translation or execution of programs is invoked and the executing units are controlled;
— The size or speed of the object code, or the relative execution speed of different language constructs;
— The form or contents of any listings produced by implementations; in particular, the form or contents of error or warning messages;
— The effect of unspecified execution;
— The size of a program or program unit that will exceed the capacity of a particular conforming implementation.
