The WLanguage Trace function lets you display information during an application's execution. This function is often used during the development phase of an application.

On the other hand, a lot of developers are aware of the possibility of customizing how the trace works. This customization is done with the TraceStart function of WLanguage.

// The trace window is displayed 

// on top of the other windows

// and a trace file is saved

TraceStart(trWindow+trTopMost+trFile, 

  fExeDir()+["\"]+"TraceExecution.txt")

You can:

• Displaying the trace inside a window, is the default behavior with the trWindow constant

• Save the trace in file with the trFile constant.

• Disable the trace by programming with the trDisable constant
