The   'do'  command is the common way to do this

repeat with k = 1 to 10
     -- build thisVar for this loop
    do  "put thisVar into newVar" & k
end repeat

You can also use
line k of fld storageFld
line k of aggregateVar
set the k of this card to thisVar
as you have done, use a multi dimensional array

Minor advantage to custom props is they can be stored in the stack  
file.  This is good for bulding things like a list of path names and  
ftp site URLs that need to be kept with the stack and are not part of  
user data or preferences.

Hope this helps
