I'm finally getting back to my 3.13B11 to 3.13.8 upgrade and tackling
all the interesting little problems introduced therein.  This one is
a bit more perplexing, so I'd like to ask about it before throwing
a fix at it.  I'll also present a simplified case, rather than the
convoluted one in my system.

The test case database is simply this:

an mbbi VAL is connected to a stringIn INP
an mbbo VAL is connected to a stringOut DOL

Both the mbbi and mbbo have a few enum strings defined. 

In 3.13B11 I get strings in the string records in either case.

In 3.13.8 I get strings with the mbbi, but get the corresponding 
numerals in the stringOut record with the mbbo. You can imagine what 
this does to downstream processing that expects strings!  If I use 
dbgf or caget, I do get strings right out of the mbbo.

I guess the first question is whether there has been a change in how
these record interconnections are supposed to work.  If so, I'll just
have to switch all my mbbo's to mbbi's in cases like this.

And, the second, most obvious, question is what am I doing wrong!
This is also, by far, the most likely case.  

Thanks for any help on this one.

Bill
