ISPF doesn't maintain DB2 tables; DB2 does.

Why *isn't* it a limitation of ISPF? ISPF is the user interface to
the mainframe, in just the same way as Windows is the user interface
to the PC. If I'm working on my PC and I click a PDF document,
Windows opens the Adobe reader.

Windows does not do this on its own. Windows has no clue how to read
a PDF file. You have a program that knows how and this program tells
Windows when you see a file that ends in .pdf then you need to execute
me.
I know that Windows doesn't read the PDF file. In the above I said
"Windows opens the Adobe reader".
The point that was being made by the original poster was that regular
ISPF only keeps track of files that ISPF knows how to deal with. For
anything else (e.g. DB2 tables) he has no way to keep track of whats on
the mainframe other than (a) purchase a vendor product or (b) write a
program.
I may still be missing the point. Just how is Windows any different? If
you buy Windows from a store and install on a PC, download a PDF file,
double click it, what will happen? Nothing. Windows has no way to keep
track of whats on it with out installing either a purchased,
self-written, or a free program.
You need to install something that in most instances, not all, will tell
Windows what to do.
