YACC 4.1 R 2 — Stephen Johnson / QL port
Floppy IMG derived from archived files. Mount as FLP1 and boot using Minerva 1.98a1 ROM, 640 KiB emulator RAM and Toolkit II 2.32. Generated a 4457-byte C parser from a grammar with token NUMBER. The report contained three states and zero shift/reduce or reduce/reduce conflicts. Checked the generated token definition and yyparse function. Compilation and execution of the generated parser on QL were not tested. Basic functional check in sQLux, not full validation or a physical-hardware test. Audio untested. ROMs are not included.
