It actually returns a date value. The format for the display of Date expressions is controlled by SET DATE TO command that has default setting of AMERICAN (MM/DD/YYYY). If you want to have DD/MM/YYYY format for whole application than use SET DATE TO DMY. See SET DATE TO topic in the help for details.
IF you want just have the date shown in DD/MM/YYYY format only in that place than you'll have to convert your numeric date to the character string

RIGHT(STR(lnDate,8),2) + "/" + ;
	SUBSTR(STR(lnDate,8),5,2) + "/" + ;
	LEFT(STR(lnDate,8),4)
