sequence definition
     A sequence definition creates a sequence identifier and creates a pattern file
    for each sequence identifier.
    Multiple sequence identifiers can be created in the same hierarchy or
    in lower hierarchies.
    A sequence definition can include subordinate sequence identifiers,
    set variables in place to create pattern content.

   (1) Generation of sequence identifiers
      Underneath the file identifier is the sequence identifier.  
      If it's just a file identifier, create a sequence identifier underneath it
      

       Select File Identifier: $File[1] in the above figure.
      Click menu -> "Create Sequence Identifier" under Output.
        

        Or, right-click in the File Identifier, Sequence Identifier,
       Title screen and click "Create File Identifier".
              

       A sequence identifier $Seq[1] is generated.
       

       Sequence identifiers can be created in the same hierarchy or
      lower in the hierarchy. If you want to create it in the same hierarchy,
      after selecting the sequence identifier,
      click Menu -> "Create sequence identifier" at the following position in the output.
       

       Or, right-click in the File Identifier, Sequence Identifier, Title screen and
     click "Create Sequence Identifier at...".
       

       $Seq[2] is created at the following position.
       

       If you want to create it under $Seq[1] in the above figure,
      after selecting the sequence identifier,
      click Menu -> "Create sequence identifier" under Output.
              

        Or, right-click in the File Identifier, Sequence Identifier, Title screen and
       click Create Sequence Identifier underneath.
       

       $Seq[3] is created under $Seq[1]. If you select $Seq[1] here,
      $Seq[3] created in the lower sequence of the sequence identifier contents
      on the right screen will be displayed.
             
      Select the sequence identifier (here, $Seq[3]) set for the subsequence.
      Move the cursor to the location where you want to insert
      the lower sequence content in the content,
      and press the lower sequence setting button to set the sequence identifier
      (here, $Seq[3]) to the content.

 (2) Setting variables
       Select the variable you want to set in the pattern file in the setting variable
                  

       Click the Set Variable button to set the variable.
