Return the number of loaded EK tables. 

   EK 

   Variable  I/O  Description 
   --------  ---  -------------------------------------------------- 
   n          O   Number of loaded tables. 

   None. 

   n              is the number of loaded tables.  The count refers 
                  to the number of logical tables; if multiple 
                  segments contain data for the same table, these 
                  segments collectively contribute only one table 
                  to the count. 

   None. 

   This routine is a utility that provides the caller with the 
   number of loaded tables.  Callers of ektnam_c can use this count 
   as the upper bound on set of table indices when looking up table 
   names. 

   1)  Suppose we have the following list of EK files and tables 
       contained in those files: 

          File name        Table name 
          ---------        ---------- 

          FILE_1.EK        TABLE_1 
                           TABLE_2 

          FILE_2.EK        TABLE_1 
                           TABLE_3 

          FILE_3.EK        TABLE_2 
                           TABLE_3 
                           TABLE_4 


       Then after loading these files, the call 

          ekntab_c ( &n );

       sets n to the value 4. 

   None. 

   None. 

   The returned count is based on the currently loaded EK files.
