This is easy enough when you want to get the horizontal or vertical 
location, but it's more cumbersome when you want to set one of them. I 
always wanted to have the locH and locV properties, so when I learned 
about getprop and setprop, I wrote this and use it in the main stack 
script of my projects:

-- virtual properties locH and locV

getprop locH
   return item one of the loc of the target
end locH

setProp locH h
   get the loc of the target
   put h into item one of it
   set the loc of the target to it
end locH

getprop locV
   return item two of the loc of the target
end locV

setProp locV v
   get the loc of the target
   put v into item two of it
   set the loc of the target to it
end locV

These can make your resize handlers a little easier to write, and to 
understand. Just get and set these properties as you would any other, 
eg, set the locH of grp "controls" to the locH of this card.
