- WHAT IS BISON?
-
- Bison generates a table driven parser written in 'C' code from
- a grammar specification. It is upward compatible with Bell
- Laboratories YACC.
-
- WHAT DO I NEED IN ORDER TO USE IT?
-
- Three files are required:
-
- BISON.EXE, ( the executable file )
- SIMPLE.PRS, ( template for simple, non-reentrant parser )
- HAIRY.PRS ( template for reentrant parser )
-
- They may all be in the same subdirectory, or the parser templates,
- SIMPLE.PRS and HAIRY.PRS, may be located elsewhere. In the latter
- case, you must specify their full path/filename in the environment
- variables BISON_SIMPLE and BISON_HAIRY. Using only the subdirectory
- path is insufficient.
-
- EXAMPLE:
-
- If SIMPLE.PRS is located in C:\usr\tools\bin,
- then you must issue the DOS command:
-
- set bison_simple=c:\usr\tools\bin\simple.prs
