=={{header|ActionScript}}==
ActionScript does not have a built-in way to repeat a string multiple times, but the addition operator can be used to concatenate strings.
===Iterative version===
<lang ActionScript>function repeatString(string:String, numTimes:uint):String
{
var output:String = "";
for(var i:uint = 0; i < numTimes; i++)
output += string;
return output;
}</lang>
===Recursive version===
The following double-and-add method is much faster when repeating a string many times.
<lang ActionScript>function repeatRecursive(string:String, numTimes:uint):String
{
if(numTimes == 0) return "";
if(numTimes & 1) return string + repeatRecursive(string, numTimes - 1);
var tmp:String = repeatRecursive(string, numTimes/2);
return tmp + tmp;
}</lang>
=={{header|Ada}}==
In [[Ada]] multiplication of an universal integer to string gives the desired result. Here is an example of use:
