Example

variables

 real x, y, dummy;

code

 y = int (x);

 x = sin (time);

 

 if time > 7 then

         dummy = settoolsetting ('integrationmethod.Euler.stepsize', 0.1 );

 else

         if time > 6 then

                 dummy = settoolsetting ('integrationmethod.Euler.stepsize', 0.01 );

         else

                 if time > 5 then

                         dummy = settoolsetting ('integrationmethod.Euler.stepsize', 1 );

                 end;

         end;

 end;
