This part of ISO/IEC 13719 defines the binding of the Portable Common Tool Environment (PCTE) interfaces, as specified in ISO/IEC 13719-1, to the Ada Programming Language. A number of features are not completely defined in 13719-1, some freedom being allowed to the implementor. Some of these features are specified as implementations limits. Some constraints are placed on these implementation limits by this part of ISO/IEC 13719.
