Evidently not many of the community are interested in this feature, but still . . . could you add my vote for this capability? I find it (at times) useful to reference a line number in error messages. Note: I'm not using Keyword testing.
Actually, based upon https://community.smartbear.com/t5/TestComplete-Feature-Requests/Line-Numbers-in-Keyword-Tests/idi-p/97486, this does have some significant support here in the community and the SmartBear folks have marked it that it will be implemented at some point in time. If you haven't voted there yet, please do so.
Yes please do this. As someone used to working with VS and other editors (or even just excel), it seems glaringly absent.
While there is logging that will help you get to certain areas of test failure, having line numbers is very helpful for teasing out more complex issues.
Hopefully this would be easy to implement and roll into an update. :-)
