How can I report an active line number?

[Steve_Block]

I've seen this used before, so I know it is possible. When I have a code failure I would like to be able to report an error trace to the operator, which includes the current line of code where the error occured. How can I obtain the current line number for code executing in CVI?

Your looking for the __LINE__ macro.  there is also a __FILE__ and __FUNCTION__

It works. Thanks.

With regard to error reporting, here you can find some personal tips.

Also, take a look at this post that discusses the use of __FUNCTION__ macro in CVI8.5
