I need to read a vsam file with alternate index. Both the base file and alternate index file have DDs in the JCL.
1. do I need a select statement for the alternate aix file or just the base file and indicate the alternate key?
2. If I need to have a select statement for the alternate aix file, should the START statement on the alternate aix > alternate key?
3. If #1 is no, should the START statement on the base file where key > alternate key which is defined in the select statement?
4. Should the READ NEXT be the base file or the alternate aix file?
