[Scilab-users] strange behavior of function xstring

[grivet]

Hello,
I have noticed the following strange behavior of function xstring.

This piece of code works fine:

         clear; clf();
         s = "A";
         plot2d(0,0,-1,"010"," ",[-2,-2,2,2]);
         xstring(0.5,0.5,s);

This one does not (simplified exemple, no useful purpose):

         clear; clf();
         function etiq(x,y)
             s = "A";
             xstring(x,y,s};
         endfunction
         plot2d(0,0,-1,"010"," ",[-2,-2,2,2]);
         etiq(0.5,0.5);

Scilab stops with error message

         xstring(x,y,s};
                !--error 2
         Facteur invalide.

What do I do wrong?
