TSO Interface 59
Invoking and disconnecting from the TSO interface
or Enter key is pressed. You can edit the input line (before it is entered) in one
of the following ways:
• Use the TSO input edit conventions defined in the TSO profile.
• Reset the EDIT parameter to 1 or 5 (see the Model 204 Parameter and
Command Reference Manual) and use the Model 204 input editing
conventions.
Backpaging
TSO supports the Model 204 backpaging feature. (For more information about
backpaging, see “Backpaging” on page 7). Backpaging is available through
TSO only if the system manager sets the NBKPG (number of backpages)
parameter to a positive number on User 0’s parameter line during system
initialization (see the Model 204 Parameter and Command Reference Manual).
In addition, the user must have the OUTLPP parameter set to a positive
number.
Occasionally a displayed backpage can contain more lines than the original
display of the page contained. This can occur when the attention key is used to
interrupt output from Model 204. Output lines can be generated by Model 204
during the delay between TSO’s receiving the attention interrupt and
Model 204’s receiving this interrupt from TSO. These lines are ignored by TSO
but are stored in the backpage buffer.
Disconnecting
To disconnect from the TSO interface, follow these steps:
1. Log out of Model 204 in the normal way by entering:
LOGOUT
or:
LOGOFF
Model 204 acknowledges the command as shown in the preceding
sections.
2. To close the TSO connection to Model 204, enter:
DISCONNECT
or:
DISC
The interface then releases the connection and returns control to TSO.
If the interface detects that Model 204 has terminated while a connection is
active, the following message is issued, and control returns to TSO:
