  • When NLSSORT is specified, the collating sequence is determined by the LANGID and SRTSEQ parameters of the CRTCBLMOD and CRTBNDCBL commands.
  • When the literal phrase is specified, the collating sequence established by the specification of literals in the alphabet-name clause is used for all nonnumeric comparisons.
  • When STANDARD-1 is specified, the ASCII collating sequence is used for all nonnumeric comparisons.
  • When STANDARD-2 is specified, the International Reference Version of the ISO 7-bit code defined in International Standard 646, 7-bit Coded Character Set for Information Processing Interchange is used.
