 ## -remarks
+The *positionList* argument varies depending on whether a horizontal or vertical ruled line is being drawn.
+
+For horizontal ruled lines, *positionList* consists of comma delimited numbers (units of measure are defined by the **MapMode** property),  which denote the starting position and length of each line. Each pair is followed by a semicolon if multiple ruled lines are specified. The pattern is repeated for all additional horizontal ruled lines. Consider this example:
+
+```csharp
+positionList = "0,500"
+``` 
+
+This *positionList* would result in a ruled line starting at MapMode unit position "0" continuing for 500 MapMode units of length. Here is another example demonstrating multiple horizontal lines:
+
+```csharp
+positionList = "0,200;300,100"
+``` 
+
+This *positionList* would result in a ruled line starting at unit position "0" and continuing for 200 units in length. Then, another line would begin at position 300 and continue for 100 units in length.
+
+For vertical ruled lines, *positionList* consists of comma delimited numbers (units of measure are defined by the **MapMode** property) which denote the positions for the vertical drawn rules line(s). A continue vertical ruled line will be drawn from each position for the print lines that follow, until the vertical rules lines are changed or terminated by a call to **DrawRuledLine** or a ruled line escape sequence. An empty string in the *positionLine* argument causes the vertical ruled lines to be terminated. Consider this example:
+
+```csharp
+positionList = "0,100,400,500"
+```
+
+This *positionList* results in four drawn ruled lines starting at unit positions "0", "100", "400", and "500" when each line of data is printed.
