There is much too much data to pore over manually, and more manual work is necessary in order to convert the CCHH values found into data set names. You have to scan through VTOC extent listings. Very time-consuming and error-prone. I was hoping you would mention the name of some current tool. I use GTF to analyze one channel program at a time to find out why it failed, how long it took to complete, if it transferred all the data I thought it would, etc. I would never dream of using GTF to do data set level analysis unless I first developed, or had access to, a tool to reduce the data down to some kind of summary form and also to scan VTOCs to convert CCHHs into data set names. Both of these tasks are non-trivial.
