EvalArgs fails

[imendez]

Hi,

I've found an error in a TOL function called "EvalArgs" when opening the SADD "concept viewfinder" ("visualizador de conceptos").

I don´t know exactly where the problem is, but it's very easy to reproduce it. You just hace to charge SADD project, open the "concept viewfinder" and watch the output log file.

Regards.

SADD is not a public project.
Could you send the sources?

Thanks in advance,
Daniel

Hi Dani,

I can´t send SADD sources because, as you say, it's not a public project.

But, as I said in my first message, the error is not in SADD code but in EvalArg function. This simple code shows it:

Real a = 4; #1
Real b = 5; #2
Real r = EvalArg(+, a, b ?); #3
Real r_ = EvalArg("+", a, b ?); #4

Line #3 returns a syntactic error and line #4 returns an unknown value (?).
Curiously, line #4 works right in version 1.1.4., but line #3 doesn´' work in any version, although it's written just as EvalArg description says:

"
EvalArg {Anything EvalArg(Code funcion, Set argumentos)} {} {Devuelve el resultado de evaluar una función con los argumentos dados.

Ejemplo:
Anything x = EvalArg(+,a,b?);
"

Thus, I think that the description of EvalArg is wrong and the behaviour of the function has change from 1.1.4 version to CVS version.

Regards.

Thanks Iván, that's enough. I'll care of it.

Sorry

This bug is due to an improvement in BText security that I introduced a few weeks ago. I solved it in Group and BinGroup but not in EvalArg because I don't use it.

Thanks to report it.
