Hello! 

First I want to thank's to Mattias Kregert and to Alvaro Herrera Munoz for the last help.
For reasons of health I have not been working.

Now, that I'm working again I have a new problem. If someone can help me I thank you a lot.

I want to work with array's and I can't do this simple thing:
*********************************
DECLARE

saidas integer[5];

BEGIN

*/ error in "["  */

saidas [1]= 5;
a = saidas [1];
saidas [1] = '';

RETURN a;

END;

*********************************

Thank's and sorry for my bad English,

Alexandra
