I could solve this by experimentation but it would take a bunch of work. I am hoping someone here knows the answer.
Under dynamic concatenation (https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.4.0/com.ibm.zos.v2r 4.ieaa800/concat.htm) it says "The name associated with the concatenated group is the ddname that was specified first; the other ddnames are no longer associated with any data set." I wanted to confirm that second part: if I concatenate DD BAR to DD FOO, then DD BAR is no longer allocated, right? Here's what makes me wonder (and wonder about an RCF): in the next section, https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.4.0/com.ibm.zos.v2r4 .ieaa800/permcat.htm, it says "A group with the permanently concatenated attribute has the following characteristics: ... Except for the first data set in the concatenation, the data sets in the concatenation are no longer associated with their original ddnames." Is that "no longer associated" only true for permanent concatenations, or is that sentence here redundant (and therefore confusing)?
