This command forces all currently open and non-frozen data explorer and monitor windows to re-evaluate, halting the process, if necessary, to get the information. If the process halts, it resumes after refreshing the windows. This provides a quick and easy way to update your data explorer windows to their current values without having to manually halt the process and resume. This feature may not work under all circumstances.
If interval is specified, then the debugger automatically updates data explorer windows approximately every interval seconds while the program is running. This is a useful way to monitor the value of a variable continuously while the program is running. To deactivate the automatic update, specify interval to zero.
