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
