This example shows how to access, create and manipulate TestStand TemporaryGlobal variables with the TestStand Engine's TemporaryGlobals property. Engine.TemporaryGlobals are very similar to StationGlobals except for the fact that they are NOT persistent. StationGlobals' maintain the last value written to them whenever the TestStand Engine shuts down by storing their values in \Cfg\StationGlobals.ini, whereas TemporaryGlobals only exist in memory and are lost when the TestStand engine shuts down. In the latest version of TestStand (2.0.1f1) TemporaryGlobals are not accessible through TestStand expression statements nor can they be browsed for in the expression browser. TemporaryGlobals are strictly TestStand API ActiveX objects only and cannot be manipulated within TestStand Expressions like StationGlobals.

The attached example files consist of two separate sequence files, a LabWindows/CVI step code module and a LabVIEW step code module that all share the same TemporaryGlobal value during execution. To use the example, open the "TemporaryGlobals.seq" file in the TestStand Sequence Editor and execute its MainSequence with the Execute >> Run MainSequence menu option.
