The for..in loop construct can be used to traverse a table, e.g.:

local (s = "");
local (adritem);
local (adrdata = @scratchpad.fruit);
for adritem in adrdata {
	s = s + "<TR><TD>" + nameOf (adritem^) + " ";
	s = s + "<TD>" + string.replaceAll (adritem^, ",", "<TD>") + cr;}
s = "<TABLE>" + cr + s + "</TABLE>";
