The unlimited long is the unique problem or is there another drawbacks?

Yes, I wrote bad the definition in the email (let rec unir c ac = 
ac^(Char.escaped c);;), but I have understood that, any case, this is a 
bad idea.

No, my parser works over all the file content. I want to read formulas 
like the following:

((p | (r -> t)) &
(q | (t -> s)))
-> ((p & -(q -> -t)) |
(r -> ((q -> (s | r)) & s)))

For example, I have a file of 752Kb with 770028 characters and I forget 
the newline char to reduce the size of the resulting string. So I don't 
know if I can apply the Chirstoph and Pietro ideas directly.

I think that the Markus suggestion is better for me, because I have 
never worked with ocamllex. By the way, can I obtain benefits in 
efficiency using ocamllex? because in this case I'll learn to use it.

Thanks for all answers
