Subject: Stopping an if statement

I have a series of functions I want to complete if a certain statement is true, In this case it is

if  p(i,j,k) <= -1
 How do I stop the loop after this has been proven true only once?  I only care about the first occurence of this being true in my matrix, only at that point do I want to run my other functions.   Thank you.
