Truth is I guess it doens't much matter though wouldn't you have to be running the JavaVM in order to run your Java shell?

The systems actually have both unix(using tshell)and solaris on them. So now I have to start working with java and pico editor but I guess I should be happy since in another class I have to use lex and yacc(then prolog,lisp,and ada).

Lex and Yacc.... I used Lex and Yacc when I did the shell. If I can promise anything it is that I will NEVER use either lex or yacc for anything again https://www.sharkyforums.com/images/.../2005/06/5.gif

Any ideas where to get some info on using the two? I would by a book but I only need it for part of the class.

"A Compact Guide to Yacc & Lex":

bison and flex are yacc and lex semi-clones:

there are probably more docs floating around various other fsf/gnu sites as well.

Good luck (and my condolences :)

Thanks for the sites. I can't wait until we are done with lex and yacc but then we move onto Prolog.
