Hello everyone

I am trying to create a general fetch-module that is supposed to update
up to 8 DB2-tabel and VSAM-files, and sends PUT SKIPs for each call. The
number of tables/files to update will change over time, so I need a
fetch module.

+-------------+    +--------------+    +-----------+
| MAIN-MODULE |--->| FETCH-MODULE |<-->| VSAM-FILE |
+-------------+    +--------------+    +-----------+

My problem:
 is that I can't seem to get fetch modules to use streams nor files. The
DB2 I/O part shouldn't bee any problem (so I've heard).

How can I use streams (put skip) in my fetch modules?
- I Found out that if I use a put skip statement i my main-module it
doesn't crash.

How can I use VSAM-files in my fetch module?
- I tried declaring, opening in the main-module and read-/writing in the
fetch-module. Result:Protection exception.
- I tried declaring, opening and read-/writing in the fetch-module.
Result:Protection exception.

If I can't use VSAM-files, how can it be that DB2 is usable when there
is VSAM beneath DB2?

There are some restrictions on what you can do in FETCHed routines with files (and
controlled variables). The programming guide has more details on this, but if you want
to open a file in main and and use it in a FETCHed routine (or vice versa), you should
probably do this by passing a FILE VARIABLE to the FETCHed routine.
