Minor suggestion to that:

X = DOW(Date(),2)
store rgb(0,0,255) to  ([Thisform.Label]+TRANSFORM(x)+ '.BackColor')

E.g. in this case you don't need to use macro.

If you need to invoke a method, then I usually do:

luRetVal = evaluate(([Thisform.Label]+TRANSFORM(x)+ '.MyMethod()')

And if you need to do lots of things with that object, you can do

loLabel = evaluate(([Thisform.Label]+TRANSFORM(x))

with loLabel
   .visible = .t.
   .backcolor = ...
   .refresh()
endwith

I dislike macros if they used in the context they should not be used. It makes code harder to maintain...
