Compiler

I'm confused with another task. This time the task is coming from Compiler subject. I have to parse some number and classify those numbers is it legal or illegal from Pascal point of view of real constans. I'm using regular expression with PHP since i feel that web-based application is more simple to develop and debug instead of standalone application, such as Visual Basic or Delphi. These applications are not multiplatform, so i picked up web-based application which is multiplatform as long as you have your browsers ready (i'm wondering, what computer who doesn't have any browser available?)

I've found some of the regular expressions using PHP manuals and Stevens's book (Regex). Thanks once again. I'm trying to modify this regex pattern to suit my task's requirement.

Well, anyway i missed my first class because i forgot that there were a class, since in the last two weeks, there were no class due to my lecturer hasn't came back from his homeland, Deutch. I remembered that i had a class at 1 PM and the class started at 10.30 PM. In that time, i was playing Zelda: Ocarina of Time. Well, that's my first idiot thing in this semester. I hope there will never be any stupid things again.
