Add Sequence allows you to add new sequences to the Batch Grid.  Generally speaking, sequences represent entirely different problems, e.g., the NeuroShell 2 examples NYSE and ELECTRIC.  Sequences are displayed as pages.  Each page has a tab that displays the sequence name.  When you elect to add a new sequence, a dialog will appear asking you to type in the name of this sequence.  Enter the name and click OK to continue.  Click CANCEL to ignore the changes.  After adding a sequence, you may proceed to add the problems in that sequence.
