Pascal-S

[Hisashi Nakai <nakai@slis.tsukuba.ac.jp>]

Hi Etienne and everyone,

  We developed a Pascal-S compiler using SableCC.
  It is available via 

http://www.slis.tsukuba.ac.jp/~nakai/Pascal-S.tar.gz

  It emits Pascal-P4 code.

  You can get a P4 interpreter via 

http://www.cwi.nl/~steven/pascal/

  How to use the Pascal-S compiler :

1. expand the tar.gz file.

[ex]
% tar zxvf Pascal-S.tar.gz
(or % gzip -cd Pascal-S.tar.gz | tar xvf )

2. move to Pascal-S directory and then execute sablecc and 
   compile the sources.

[ex]
% cd Pascal-S
% sablecc pascal.grammar
% javac pascal/Main.java

3. compile a Pascal-S source with the Pascal-S compiler.

[ex]
% java pascal.Main sample.p

4. then you can get a P4 code in a file named "prr".
   So you can run P4 interpreter as follows.

[ex]
% mv prr prd
% pint < /dev/null   (or pint < input)



Have fun!
