Like many storage admins, reading LISTC output and matching the keywords is indeed an exercise. ;-) >Could someone tell me if there is a doc where I can match the LISTCAT with the >DEFINE CLUSTER parms? Perhaps others know of such document, but I believe there is a CBTTAPE program which can recreate a VSAM dataset based on LISTC output. LISTC show the 3 parts - CLUSTER, DATA and INDEX. The sequence of the 3 parts are in the same order as listed (for DEFINE CLUSTER) in the book, but of course the keywords and the order of keywords are not the same. What you can do for now: Just concentrate on one part of LISTC output, say DATA and finish the matching and move on to the next part. The ATTRIBUTES part should be easy - the keywords are generally the same. The second line 'IN-CAT' in LISTC output is actually the LAST keyword, CATALOG(<cat>), of DEFINE CLUSTER. The keyword content of NAME in both DATA and INDEX part are shown in ASSOCIATIONS (in the first few lines of LISTC). I think you should list all the words (and in which of the 3 parts of LISTC) you're struggling with, so we can give you the right keyword for that word.
