Rules for Processing Each Data Record (When Adding or Changing)
If a distribution definition exists for the distribution identifier, that definition is used; otherwise, a new distribution definition is created with all data fields initialized to blanks.
To create a distribution list, specify the DISTID and LDISTID parameters. The LDISTID, LODISTID, LENTNO, LRELNO, LNDISTID, LDEST, LWRITER, LGROUP, LOUT, LRVIEW, LREPRT, and LDEL keywords are ignored if the distribution identifier is not a distribution list.
The data fields in the distribution definition for which parameters were specified on the /DISTDEF control statement are set to the values from the data record; the data fields for which no parameters were specified on the /DISTDEF control statement remain unchanged.
