Note: BKSADD and EBRBETAx are two separate, unrelated packages. Sometimes they are both in /ps/products/ibmreader/fixes, but they are not used together. BKSADD.EXEC R1.5 fixes a problem which prevented OS/390 BookServer from accessing books in sequential datasets. BKSADD adds the book datasetnames into the shelf, and R1.5 does it in a way that allows BookServer to then find the books. BKSADD.EXEC must be in fixed-80 format on the host. If you are retrieving the exec via FTP on MVS or OS/390, specify binary locsite lrecl=80 recfm=fb before getting the file.
