The LANGID keyword indicates which language identifier is to be used when the sort sequence is *LANGIDUNQ or *LANGIDSHR. The LANGID keyword is used in conjunction with the SRTSEQ command parameter or keyword to select the sort sequence table.
If *JOBRUN is specified, then the LANGID value associated with the job when the RPG object is executed is used.
If *JOB is specified, then the LANGID value associated with the job when the RPG object is created is used.
A language identifier can be specified, for example, 'FRA' for French and 'DEU' for German.
If the LANGID keyword is not specified, then the value specified on the command is used.
