+A few examples using the newly found <step> value:
+ /script for i=10,1,-1 do DEFAULT_CHAT_FRAME:AddMessage(format("%d",i));end
+Will count from 10 to 1.
+ /script for i=10,0,-2 do DEFAULT_CHAT_FRAME:AddMessage(format("%d",i));end
+Will count from 10 to 0 skipping every other number.
+ /script for i=2,10,2 do DEFAULT_CHAT_FRAME:AddMessage(format("%d",i));end
+Will count even numbers from 2 to 10.
+Examples for the 'in' version of the syntax:
+ /script myTable = {"a","b","c","d"};
+ for var,i in myTable do
+      DEFAULT_CHAT_FRAME:AddMessage("The value of index "..i.." is "..var);
+ end;
+Output:
+ The value of index 1 is a
+ The value of index 2 is b
+ The value of index 3 is c
+ The value of index 4 is d
