Creating groups and lists

A group is created when you specify it as the GROUP name in a DEFINE command or as the TO group in a COPY command (see The CEDA COPY command and The CEDA DEFINE command). For example, the command:
CEDA DEFINE PROGRAM(PROG1) GROUP(MYGROUP)
defines a program called PROG1, and creates a group called MYGROUP if it does not already exist.

These are the only ways to create a group; a nonexistent group can be named in a list, but naming it in a list does not create it.

A group must not have the same name as an existing group or list.

You can create a list in either of the following ways:
  • Use the ADD command to add a group to a list (see The CEDA ADD command). If the specified list does not exist, it is created.
  • Use the APPEND command to append the contents of one list to another list (see The CEDA APPEND command). If the appended-to list does not exist, it is created, containing the contents of the first list.

A list must not have the same name as an already existing group or list.
