The trace() function outputs debug statements, which can be read by anyone with a debug version of the Flash player. Because sensitive information could easily be exposed in this manner, trace() should never appear in production code.

Noncompliant Code Example

    var val:Number = doCalculation();
    trace("Calculation result: " + val);  // Noncompliant

Compliant Solution

    var val:Number = doCalculation();
