Finding syntactical errors -- missing arguments, arguments of the wrong type, ... -- involves either manual inspection or running a sequence to see where it croaks. TestStand could use the equivalent of a broken run arrow from the LabVIEW environment. As in the LabVIEW environment, clicking on that broken run arrow would present a list of the syntactical errors, and double-clicking on one of the entries in that list would take you to the entry itself.
