Custom properties and getProp

[David Vaughan]

I found these two corrections (line 1 and line -4) to my script which 
got it working:

getProp monthDays[monkey]
   if monkey is "Feb" then
     put word 3 of item 2 of field "theDate" into theYear
     switch
     case (theYear mod 400) = 0
       put 29 into x
       break
     case (theYear mod 100) = 0
       put 28 into x
       break
     case (theYear mod 4) = 0
       put 29 into x
       break
     default
       put 28 into x
     end switch
   else
     put the monthDays[monkey] of me into x
   end if
   return x
end monthDays

That leaves me with two general questions which I repeat with slight 
modifications:
Is "akey" in the dictionary definition of getProp meant to be a value or 
a variable? How is it passed and used?

How do I create a property (not a set) as an array in the properties 
dialogue rather than through scripting please?

thanks
David
