. Do all File Definitions have to be part of the code, or can they be created in a separate PDS and called in by a program as needed? If they can be placed in a separate PDS, what is the DDNAME the JCL uses?
Google is your friend. I searched for easytrieve copybook and got back about 3,190 results and the first one found was http://code.xmlgadgets.com/2010/09/21/e ... -copybook/ which has the DD statement, the usage, and an explanation.
