Setting custom properties

[Jim Hurley]

I would like to be able to set a custom property to an evaluated 
string. In the following lines of script:


put "apples" & cr & "oranges" into tList
put "myGroceryList" & 3 into tName
set the tName of this card to tList

It appears that Run Rev will assign tList to the custom property 
myGroceryList3. But how does it know that the name of the custom 
property is myGroceryList3 and not tName? Does it check to see 
whether tName has a value in the script?

Risky business.
