ADD SORT 

Adds a new sort item to a search item of a path.

Syntax 

     A[DD] SO[RT] DetailDataSetName SearchItemName SortItemName 

Parameters 

DetailDataSetName   is the name of the detail data set for the new sort
                    item.

SearchItemName      is the name of the search item whose chains are
                    sorted based on the new sort item values.

SortItemName        is the name of the new sort item.  It must be an
                    existing field in the data set.

Description 

Use this command to add a new sort, or to replace an existing sort item,
to a search item of a path.  All parameters are required.  If a sort item
already exists for the path, the new sort item replaces it.  The sort
item must be a data item other than the current search item for that
path.  Only data items types U, K, or X can be sort items.

Example 

     >add sort sales account purch-date 

In this example, the sort item PURCH-DATE is added to the path defined by
the search item ACCOUNT in the detail data set SALES.

Before the addition, the SALES data set entry in the schema looks like
this:

     NAME:     SALES     ,D(11/14,18);
     ENTRY:    ACCOUNT    ( CUSTOMER             ), <---- sort item to be added 
               STOCK#     (!PRODUCT              ),
               QUANTITY                           ,
               PRICE                              ,
               TAX                                ,
               TOTAL                              ,
               PURCH-DATE ( DATE-MASTER          ),
               DELIV-DATE ( DATE-MASTER          );
     CAPACITY: 504(14);

After the addition, the SALES data set entry in the schema looks like
this:

     NAME:      SALES     ,D(11/14,18);
     ENTRY:     ACCOUNT    ( CUSTOMER (PURCH-DATE)), <---- sort item added 
                STOCK#     (!PRODUCT              ),
                QUANTITY                           ,
                PRICE                              ,
                TAX                                ,
                TOTAL                              ,
                PURCH-DATE ( DATE-MASTER          ),
                DELIV-DATE ( DATE-MASTER          );
     CAPACITY:  504(14);
