Dr YACC is a useful software which deploys LR-DFA and LR1 language independent parse generators
Dr YACC is a useful software which deploys LR-DFA and LR1 language independent parse generators with capabilities to support multiple DFA/LR parse engines in a single application. Dr YACC's grammar and rich set of utilities, tools, Parser Foundation Class (PFC) parse engines, coupled with complete error and grammar statistics is the key to accelerated parser development and quality.

Dr YACC's grammar is designed to work synergistically with semantic actions, node insertion, node deletion, operator manipulation, and error recovery. Using Dr YACC to design and debug your next parser, will cut your development time to a mere fraction.

Dr YACC includes the LR-DFA and LR1 parse generators and Parser Foundation Classes (PFC) ANSI C/C++ code designed to accelerate your language development and have complete control.

In any case, deploying Dr YACC will significantly enhance your ability to develop faster, more robust parsing applications in less time for Compilers, Languages and Data Parsing applications.
