Having multiple engineers working on code is an issue for me when a person writing an expression doesn't check for errors. I myself am sometimes a culprit of this. The error doesn't show up until Teststand trys to evaluate it, some code will not show errors if the sequence flow doesn't access the step with errors.
It sure would be nice to have a tool that checks for expression errors either in the whole sequence file or a called sequence.
Why do geeks think Halloween and Christmas occur on the same day?
Because 31oct = 25dec!
