Constructing keyword strings

Use Figure 1 to help you construct the keyword string to describe DFSORT program failures.

To use the diagram:

Choose the type of keyword.
Start from the left.
Continue to work from left to right.
When you encounter parallel elements in one line, make a choice.
Type uppercase letters and special characters exactly as given.
Replace lowercase letters with the appropriate data.
Your statement is complete when you reach zero, on the right side.
