When we run a package with back-out option enabled, we sometimes ask ourselves which of the generated members name starting with a special character like '.' in the corresponding libraries are the back-out of the elements included in this package.
The answer to this question is not complicated and with the help of an EBCDIC representation table we will have most of this responded. The other necessary piece is an option that is hidden in the PACKAGE DISPLAY Panel (C1SP1000) and BACKOUT Panel (C1SP6000).
