1693	 GPL a Truly General Purpose Language	 A truly general purpose programming language GPL is described which contains facilities for constructing within the language new data types as well as facilities for operations performed upon them. The basic language is minimal in the sense that no basic element can be derived from the others with high efficiency in the object programs. Constructs like the ALGOL for-statements and if-statements are not basic they are special types of procedures. New symbols underlined words in ALGOL are implicitly defined by usage in other declarations. As part words are definable packed words are handled as easily as full words. Address variables pointers are included in full generality. programming language general purpose self-extending macro ALGOL
