Short version: is the CBT 476 corrupted or there is a job to extract further, so that these PDS members of CBT429.FILE476? (such as MACLIB, CNTL,... etc.) is generated as library for me to use as LISP program and JCLLIB etc.??
----
Longer version on accessing CBT tape mostly but NOT CBT 476 on Lisp:
After 10 years (last time I found I am asking for this in a yahoo group!), I finally see some CBT tapes and hence for most it seems to work as follows:
1. Under TK5 update 3, you download the dasd and then follow the instruction to override the related .conf (by zip -o)
2. Then after running TK5
3.? modify and submit the job as recommended
? ? ?(Strangely the ISPF cc-cc cut can cut to the clipboard but cannot insert ... hence have to retype some JCL).
4. All ok and catalog
5. ISPF =3.4 CBT429?
6. Found all the CBT tape mostly work (in the sense you can see allocation result of them)

7. some of these have no allocation info and if you s it it got error and if you e it it will say dataset not on catalog
8. But for 476, it does have allocation info and one can get into it by e i.e.?CBT429.FILE476(@FILE476) is readable
?

10. Now what to do next?? In some other PDS I browse they are just some JCL, source etc.? But the other files here are odd e.g.
CBT429.FILE476(CNTL):

CBT429.FILE476(MACLIB)

... many of these file names under this PDS seems to be itself also a library as well.??

11. For this tape is there another step I need to run to extract these "libraries" into proper libraries.
12. I must have missed one tool or one JCL somewhere to extract these:
