Cell Reference question

[Tom]

This is probably a simple question, but I have never seen it before.

I have been looking at some spredsheets sent by some co-workers,
trying to figure out their structure etc... and I have seen some cell
references where the reference starts with an =+'sheetname!e2

The + (plus sign) struck me as odd, I can't recall seeing that before.
Is there some significance to it?
Thanks
Tom

Believe it's a "legacy" behaviour for die-hard Lotus converts <g>
The "+" is not necessary ..
