I guess that you want abs(r) > 0.6, not r > abs(0.6). 

Either way, in addition to canned commands, note that the double 
-forval- technique used by Ronnie in another thread 
offers an easy direct solution. Given that you 
have put the correlation matrix into a Stata matrix 
(at least 3 ways to do that), you need a loop 
something like 

forval i = 1/10 { 
	forval j = 1/10 { 
		mat foo[`i',`j'] = cond(abs(foo[`i',`j']) < 0.6,.,foo[`i',`j'])
	}
}

which can be automated as desired.
