Operator commands
This topic describes using the /OPNDST and /ASSIGN commands as they are used with ETO.
/OPNDST
The VTAM® mode table that is used when the terminal
first logs on determines the device characteristics. However, if the
first reference to a terminal is through an /OPNDST command,
the MODETABLE operand of that command determines
the device type.
Omitting the
MODETABLE operand
on the command causes it to default, which might not be desirable.
After the terminal is in session with IMS,
the rules for block deletion apply. The device type remains set until
the block is deleted; if the terminal is closed and then reopened, IMS uses the existing block, if available.
If a block is deleted, that block is rebuilt during the next terminal
logon. As a result, the /OPNDST command can have
different results, depending on two things: - Whether the block is still available (and has not been deleted).
- Whether the exit routine or descriptor has been changed since the previous initialization.
/ASSIGN
You can use the /ASSIGN command to move queues from one terminal to another. You cannot use it to reassign a static terminal to a dynamic (ETO) terminal, or to assign a dynamic terminal to a static terminal.
