Parser returns a mistake always at the first line

[imendez]

The parser shows a curious error when the lower code is compiled:

Real a = 4;
Real b = 4;
Real c = 4;
Real d = 4;
Real e = 4;
Real f = 4;
Real g = 4;
Set sEq = ?;

ERROR: Símbolo de cierre #}# fuera de lugar en línea 8 y columna 12:

LINEA

8 > Real a = 4;

9 : Real b = 4;

10 : Real c = 4;
11 : Real d = 4;
12 : Real e = 4;
13 : Real f = 4;
14 : Real g = 4;
15 : Set sEq = ?;
16 :

The parser returns a mistake always at the first line, so the complexity of
detecting the error rises with the number of lines.

On the other hand, i don't know if upper way of creating an empty set must be
valid. The code

Set sEq = Copy(Empty);

works perfectly, but:

Set sEq = ?;

doesn't work.

In this bug report there are two different things.
The second one is not an error, between symbols and ? always must be something.
Please, change the title of the bug and send again the first part as a new bug report.

I don't know that i can change the summary. Bug accepted.

A solution of this problem has been implemented in Tol CVS repository.
I make some changes in ErrorPosition method of BParser class.
This method calculates the exact position of a syntax error.
Tol Parser need another kind of improvements about those we must talk in the next Tol
