help with yacc?

[Gregory E Leach]

I will heartily recommend the following books.  I used both of them 
to learn yacc well enough to write a large command interpreter for 
a scientific language.


The Unix Programming Environment, Pike and someone
Compiler Construction using Unix, don't remember

The titles are correct ( I think ), and you should be able to order them
from your local bookstore ( or form the UNIops bookstore ).  Another
good place to pick up unix/C books is the C users group/C users journal.
