User buffers can be used to provide input to Adabas nucleus user exit 11 and 4 and the Adalink user exits 1 and 2 (or A and B in Adabas 7 installations). The syntax of this input depends upon your user exit program requirements.
You can specify a single user buffer in a direct call. User buffer contents are merely passed onto your application by Adabas; they are not processed in any way.
For complete information about Adabas user exits 11 and 4, read User Exit 11 (General Processing) and User Exit 4 (User-Generated Log Data). For complete information about Adalink user exits 1 and 2 (or A and B), read the appropriate Adabas installation documentation.
