Question: How to not evaluate worksheet until i want

Hy everyone,

i'm writing a code wich ends with an Explore including multiple parameters (8) ; my problem is that if i want to change every parameter, elaborating time becames too long, because Maple evaluates every variation of every parameter every time.
I'm looking for something like a button, which works like this: when i change parameters in explore maple doesn't evaluate the function, and when i click the button maple evaluates one time all the changed parameters.

Any suggestion? 

Thanks in advance
