Due format.

The assignment should be returned to the instructor by email. Your work will consist of

• one main file containing all answers to questions except computer programs
• one attached file per computer program.

The main file can be

• either a text file which will be the message of your email
• or an attached postscript or PDF file.

No other formats than text, postscript or PDF are allowed. Please contact the instructor if you have any technical difficulty with these formats. The computer programs of this assignment are all input files for the flex (or lex) program and the yacc program. The preferred version of flex/lex is flex version 2.5.4. You must provide a script file or a Makefile for the construction of your applications with flex and yacc. This construction must work under Linux (with a recent distribution) or under a UNIX system of the GAUL network. You can reuse the Makefile of the archive yacc.tar.gz from the course web site. Note that this Makefile was developed with bash under Red Hat 7.3 (Linux). You should also provide a README file specifying

• which UNIX system you are using (Linux or SunOS)
• which shell (command language interpreter) you are using (tcsh or bash)

For the compilation options of flex/lex and yacc please refer to the Makefile of the archive yacc.tar.gz.
