HBO0053I The name abc is not defined.
abc is not recognized in the context where it is used. Different names might be recognized in different parts of a statement. For example, the only names that are recognized to the right of an equal sign in a SET clause of a DEFINE UPDATE statement are the names of fields in the record (or columns in the table) that is the source of the update and the names that are defined by a LET clause. The System Data Engine stops processing the current statement and continues with the next.
