The publication is a manual for using the BOBS-system, which is an SLR(1)-parsergenerator and parser. In short the BOBS-System produces a syntax-checker for a grammar in a class of contextfree grammars called SLR(1)-grammers. The syntax-checker is delivered as a Pascal program, which further contains a lexical analysis and an error-recovery. The manual describes the input format of the grammar, the grammar-checks performed and what output one might have from the parser-generator. Further a description of the most important elements of the parser is included.
