What’s In A Save File?

Note: The code accompanying this article is available for download here. Juliet wondered, “What’s in a name?” Ted wondered, “What’s in a save file?” The Display Save File (DSPSAVF) command would show me only so much, so I wrote a utility to give me more information. Maybe it will be helpful to you. It’s common for me to exchange save files with other IBM i professionals. One problem I often run into is that someone (who might be me) cannot restore a save file to their system because the save file was created for a more recent release of IBM i. I needed a way to determine this information, and DSPSAVF did not have it. Fortunately, IBM’s QSRLSAVF API lists more information than what DSPSAVF shows. My utility is called Print Save File, and it consists of three objects:
It also requires Brian Rusch’s magnificent message-forwarding commands, MOVPGMMSG and RSNESCMSG, which were published in the May 2, 2012, issue of Four Hundred Guru. Here’s a sample of the report.
