4D Insider v2004 and an old structure

[George Tiller-2]

I'm currently bug-swatting in a 4D program that was originally created
(by my client himself) in 4D v1 or v2 (US version) and simply upgraded
with each new 4D version. The previous version was v2003 and v6.x before
that, and I'm trying to get it cleaned up by making variable names
descriptive and consistent, fixing variable typing errors, etc.

I've been using 4D Insider v2004 for a lot of the renaming, and it
appears to be working ok. However, I've been seeing variables that should
no longer exist still appearing in the 4D Insider variable list, even
though no occurrences show in the left-hand list when I click on the var
in the center list.

Any suggestions for how a variable can exist in a structure without being
referenced anywhere?
