variable checking?

[Timothy Miller]

I'm at home on my dialup connection, so I haven't had a chance to 
read Rev List messages for the past seven days or so. No doubt a few 
people deserve a thank you for replies posted during that time. I'll 
get to that tomorrow.

In the interim -- a quick question. When I have a script open, I see 
a menu item "script:variable checking" I can't find it in the onboard 
documentation. No doubt it's useful at times. What does it do?

I do own Dan's book, Vol 1. Aside from that and the list, are there 
other good places to look when I get stumped by something easy like 
this?

Thanks in advance,


Tim
