-src = "if x>1 then y"
-SINPUT src; vif, " ", vcond, "then", vdo

+### Example 1: Split string with delimiter ","
 
 ```
 src = "1456,Peter,8"
+
 SINPUT src; id, ",", name, ",", age 
-print "ID: " + id
+
+print "ID  : " + id

+### Example 2: Split string with complex delimiters
+
+```
+src = "if x>1 then y"
+SINPUT src; vif, " ", vcond, "then", vdo
+print vif, vcond, vdo                       ' Output: if    x>1    y
