You have to have perl running on your machine. You can download the source code from:

http://www.perl.com/pub/a/language/info/software.html

If you are lucky they already have a compiled binary for your OS at:

http://www.perl.com/CPAN/ports/index.html

Once you have perl then open a DOS window and cd to the folder where the convert.pl code lives and type:

perl convert.pl xxx.xxx

where xxx.xxx is a text file of rules. (If xxx.xxx is not in the same folder then use the full path) A rule is defined as some text, two tabs, and a probability.

Apparently the rules file would be generated by another program and all convert.pl does is change the format and generate a new file.

first of all thank you for replying me. i was wondering whether you could help me change the code in such a way that the program will be calling the user to key in the input. the input will look like this:-
S -> ASA|aB;
A -> B|S;
B -> b|v;

*note: v is actually epsilon or could be a blank and ';' is to separte each rules.

do u think it's possible ?? thank you.

or do u think u could tell me what are the input that i should key in for the earlier code? pcfg.pl where you can get the code from the website that you've pasted on.meaning if i can execute that pcfg.pl i will have the textfile in order to run the convert.pl right ? please do reply me as soon as possible because i need to know how does this run so that i can do my assignment. Thanks you.
