MERGE special registers

Edit online

The topic describes special registers of the MERGE statement.

SORT-CONTROL special register
You identify the sort control file (through which you can specify additional options to the sort/merge function) with the SORT-CONTROL special register.

If you use a sort control file to specify control statements, the values specified in the sort control file take precedence over those in the other SORT special registers.

For information, see SORT-CONTROL.

SORT-MESSAGE special register
For information, see SORT-MESSAGE. The special register SORT-MESSAGE is equivalent to an option control statement keyword in the sort control file.
SORT-RETURN special register
For information, see SORT-RETURN.
