Maybe a .prg would be simpler - just

text textmerge to lcPrgtext noshow
define class <<classname>> as custom

<<lcProperties>>

<<lcMethods>>
enddefine
endtext
strtofile(lcPrgText, lcPrgFile)
compile (lcPrgFile)

And you get your fxp. But since we don't need to turn this into another "prg vs vcx" thread, whichever works for you is OK.
