How can i display nothing in my screen?

I am using semicolon after each comand, but i have still all the procedure to run in my screen. There is a way to make this invisible, in order to gain time?

Do you have an echo on anywhere in your code? If so, remove it and disable echoing by:

echo off
echo off all

no i haven't, but i use some commands, like Estimate and i don't know what is behind this, so i see all the estimate procedure in my screen!
