Further to my last message, one can construct one's own reference and pass that.

WITH oInter
 FOR n=1 TO .nInterOpts
   caImportFiles=[oInter.aInterOpts(]+TRANSFORM(.nInterOpts)+[) .aImportFiles]
   caInternalFiles=[oInter.aInterOpts(]+TRANSFORM(.nInterOpts)+[) .aInternalFiles]
   IF .FilesExist(caImportFiles, cImportPath, lSync) AND ;
     .FilesExist(caInternalFiles, cDataPath, lSync)
     .CleanFiles(caInternalFiles, cDataPath, cOutPath, lSync)
   ENDIF
 ENDFOR
ENDWITH

and in your function

FUNCTION FilesExist(caFiles, cPath, lSync, cUser)
		
 lnFiles=ALEN(&caFiles,1)
 IF lnFiles>0			&& Just in case
   lcErrMsg=''
   FOR x=1 TO lnFiles
     IF NOT FILE(cPath+&caFiles(x,1))
	lcErrMsg=lcErrMsg+CHR(13)+[The ]+&caFiles(x,2)+[ file. (]+&caFiles(x,1)+[)]
     ENDIF
   ENDFOR
   :
   :
   :
 ENDIF

The ability to do this oneself makes the limitation on passing properties by reference nonsensical.

Ho hum!!!!
