Index example: Grouping with a unique-weight sort sequence table

Grouping with a unique-weight sort sequence table (SRTSEQ(*LANGIDUNQ) LANGID(ENU)).

  SELECT JOB FROM STAFF
   GROUP BY JOB

When using the OPNQRYF command, specify:

OPNQRYF FILE((STAFF)) FORMAT(FORMAT2)
   GRPFLD((JOB)) 
   SRTSEQ(*LANGIDUNQ) LANGID(ENU)

The system can use either index HEXIX or index UNQIX.
