Where did my Shared Variables go?

[jcarmody]

I've inherited an AWFUL program that I need to modify.  I was successful upgrading it last year (in LV 8.5), but when I open it now I see a bunch of Shared Variables that look like this:

 Have you seen this before?  What do I need to do?

Does the LV project include the library that contains the shared variables? 

[jcarmody]

Yes.  It's the same LV Project that I used last year.

Another piece of information - the Error list says "Shared Variable '?': Not linked "

Any chance SV was bound to hardware I/O?

Weird part is that symbol displayed of SV is exactly what is on the block diagram pallettes.

Will it let you 'right click' and then Select Variable from lib in project?

[jcarmody]

Yes, and I can do that for the few of them that are wired to type-defs.  The problem is that many of them, like the one pictured, are connected to boolean constants with no hint of which variable was used.

The only reason this application uses SVs is because the author didn't know any better.  I could forgive him if he was sorry for what he did, but he was proud of it.

Ouch!  Maybe he was so proud that he framed images of block diagrams?

I made up a simple project and tried to come up with a sequence of events that could cause this.  Have been unable to do so.  I just can't figure out how the link between SV on block diagram and svlib could get blown away.

He should be proud.  He's accomplished the largest BD in the WORLD!
