Wow! I would NEVER have found this out without your intervention. 
The documentation of tables is seriously deficient IMHO - or my idea 
of what a table is for (user input and subsequent manipulation by the 
app's script) is way off somehow. Your info comes from looking under 
the hood in the RR code, which I would think of very much as a last 
resort - I didn't even know there was a revTable frontscript, or that 
the cell references and contents are held internally in an array!

Anyway thanks very much indeed.
