How to pause the loop without using delay

hello,
i'm try create "menu" lcd screen.
i'm using cycle this:




int x=digitalread(button);

if(x==high){

delay(1000);
x=digitalread(button);

while(x==low){

....
lcd.print("hello");
....
x=digitalread(button);
}}

but "hello" print blink because while cycle continue loop , printing string.

how can "pause" program (i print "hello" 1 time) , waiting new input?

thx help. (ps.sorry bad english)

quote

i print "hello" 1 time

print before while loop.
