Kurt,
I tried it n times and worked in all. I made sure I find target line in each run first :

*locate target record 1st run
lnLine = atcline('caption',properties)
replace properties ;
  with stuff(properties, ;
   at(mline(properties,lnLine),properties), ;
  len(mline(properties,lnLine)), ;
  [Caption = "I hacked scx"]+chr(13)+chr(10)+[Forecolor = 255,255,0])
*modi form and change applied - modi something in any to force save
*locate target record 2nd run
lnLine = atcline('caption',properties)
replace properties ;
  with stuff(properties, ;
   at(mline(properties,lnLine),properties), ;
  len(mline(properties,lnLine)), ;
  [Caption = "I hacked scx again"]+chr(13)+chr(10)+[Backcolor = 0,255,255])
*modi form and change applied 
* repeat n times and all worked.

BTW when saying adding property we're talking about existing but at their default properties, right?
However as I said before instead of hacking the scx for this kind of job I prefer select multiple objects and change properties approach. If it would need some automated job then aselobj() approach. Modi form to get form to designer, click on labels go to command window and :
modi comm xx

lnObjects=aselobj(arrObjects)
for ix=1 to lnObjects
 oObject = arrObjects[ix]
* do whatever with object
endfor

With this approach you could also read-writemethod, cloneobject etc.
