Changing stream definitions

When altering streams using the AMASPZAP service aid, keep the following information in mind:

Session Manager has nine streams, indicated by the fullword at label ADFIDSTR in module ADFMDFLT. It is initialized to X'00000009'. Do not change this value. If it is changed, unpredictable results occur.
The following stream names are required:
- TSOIN
- TSOOUT
- SMIN
- SMOUT
- EXTRA1
- EXTRA3
- HEADER
You can change the maximum number of lines, lines per IDB, stream size, and stream header, but you cannot change the stream names, stream type, or stream flags.
The remaining two streams, MSG and EXTRA2, are not required. You may change any definitions for these two streams except their stream names.
The stream headers must remain the same length as currently defined.
