The Glb.Fail built-in segment attribute contains "*****". In most cases this is the value that Glb.Status is set to when an error occurs. This can be tested with the logic:
If Glb.Status = Glb.Fail
Note: Not all errors cause Glb.Status to contain "*****". In some cases, Glb.Status contains a 5 character message. The user is advised to test for Glb.Status not equal to spaces when checking for errors, for example:If Glb.Status not = Glb.Spaces
