008D830A Set "<set-name>" is undefined or used out of context.

    Explanation:

    Your DEC DATATRIEVE record selection expression invalidly
    referred to an existing set.

    User Action:

    To use a record selection expression containing a set name, you
    must:

    o  Establish a single record context in the database by
       specifying a set occurrence in one of the domains that make up
       the set. Use a FOR statement or the FIND and SELECT statements
       to specify a single owner or member record and establish the
       context.

    o  Make sure the domain name you specify before the OWNER or
       MEMBER clause is correct for that set. Use the SHOW SETS
       command to see which domain, collection, or list in the set
       is the owner and which is the member. You must use the OWNER
       clause after the owner and the MEMBER clause after the member.
       You can use either the MEMBER or OWNER clause with the WITHIN
       clause.
