For complex situations I prefer methods. For long expressions you can simply use text..endtext or string concatenation.

Your case however is neither complex nor long. You misguided everybody with title I guess. Solution was much simplier:

TEXT TO .DYNAMICBACKCOLOR TEXTMERGE NOSHOW PRETEXT 15
(IIF(THIS.ENABLED AND !THIS.READONLY,
   <<goApp.nBackColorFld>>,
   <<IIF(goApp.nOSVersion < 5.01, goApp.nBackColorForm,  THIS.BACKCOLOR)>> ))
ENDTEXT
