Do you have in mind some options like: "EvaluationMonitor is an option for various numerical computation and plotting functions that gives an expression to evaluate whenever functions derived from the input are evaluated numerically." <http://reference.wolfram.com/mathematica/ref/EvaluationMonitor.html?q=EvaluationMonitor> or "StepMonitor is an option for iterative numerical computation functions that gives an expression to evaluate whenever a step is taken by the numerical method used." <http://reference.wolfram.com/mathematica/ref/StepMonitor.html> Also the function *Monitor* (new in v6) can be used: "Monitor[expr, mon] generates a temporary monitor cell in which the continually updated current value of mon is displayed during the course of evaluation of expr." <http://reference.wolfram.com/mathematica/ref/Monitor.html> The following tutorial might be useful too.
