SuperC may be able to help. It will require a listing of all data sets on a volume and then generation of appropriate JCL and control cards. In rare cases identical hash sums can be generated, but certainly any differences point out changed data sets.
>From the manual (See Appendix A in ISPF User's Guide Vol. II.): SuperC can generate a 32-bit hash sum per data set or member using the File compare type. Data sets compared on a nonconnected processor, using SuperC, should have the same hash sums if they are identical. A File comparison of any data set to determine a hash sum can be done by specifying the same data set as both new and old. The hashsums of files can be used to compare two files that are not physically on the same system. If the hashsum of a file on system A is different from the hashsum of a file on system B, then the files can be said to be different. If the hashsum of the files are identical, there is a high probability that the files are the same. You should also compare the number of lines and number of bytes as secondary confirmation that the files are the same -- -- Don Imbriale temporarily retired On Wed, Dec 30, 2009 at 7:02 AM, Richards, Robert B. < [email protected]> wrote: > Paul, > > That's a start.
