The Pascal Standard (ISO/IEC 7185) does not completely define all features of the language. Some features are implementation-dependent. Below are links to the definitions of how Irie Pascal treats all implementation-dependent features. Each definition has the following format:
First the official description of the feature is taken from ISO/IEC 7185 and displayed in red. This is followed by a simplified description, if the official description is unclear or requires the reader to have a copy of ISO/IEC 7185. Finally a statement describing how Irie Pascal treats the feature is at the end.
