Two wire LCD interface in Proteus

[zuisti]

My aim was to control a simple 2x16 char LCD and a traffic light,
and query two switches, all with the smallest PIC (12c508).
 
The challenge was to fit the required code and circuitry to this chip.

Sorry but I wrote the program in pure assembly.
This is my first PIC work and it doesn't a perfect prg, hence I don't attached it.

Can somebody writing this prg (this functionality) in Basic or C ?
My (hard optimalized) assembly prg's lenght is 453 words.

The Proteus 7.1 sp2 simulation (ZIP) is attached here.

Remark:
The full (with source) is attached yet (look at my next post here).

Thanks Mehdi for the links!

I attach my full Proteus simulation now with source too.
It is in assembly but (I hope) well commented.

Do not forget usihg the two switches...
