You can erase a logical message using the message terminate command. If
the logical message is security protected, it is terminated only if your identification
or class matches that in the message. After an erase, the last message still
in the chain is displayed. The format of the message terminate command is
as follows:

CSPG MSGTERM
>>-CSPG--Msgterm--+-A-+--+---------+---------------------------><
+-B-+ '-,hhhhhh-'
+-C-+
+-H-+
'-R-'
- Msgterm
- A user-defined transaction identifier (1-7 characters) for the
message termination transaction (for example T/) as defined in the PGPURGE system
initialization parameter.
- A
- Terminates all logical messages destined for and being displayed on
that terminal (including routed messages not yet displayed). The following
message is received when termination has been completed:
DFHTP4122 Requested purge completed successfully
- B
- Terminates the logical message being displayed on that terminal and
all logical messages chained to it. This does not include routed messages.
Whenever you have finished with all the output from a transaction, you should
terminate the base message by entering a command of the form msgtermB. If the message has been built using a SEND PAGE command with the OPERPURGE
option omitted, you can terminate the paging session by entering data other
than a paging command.
- C
- Terminates the current (level) logical message and any messages chained
below it.
- H
- Terminates all logical messages chained to the base logical message
being displayed on that terminal. The page of the base message that was most
recently displayed is redisplayed at the terminal.
- R
- Terminates all logical messages queued for immediate delivery (routed)
to the terminal. The page that was being displayed at the terminal is redisplayed.
- Hhhhhh
- The 6-digit hexadecimal identifier of a specific, undelivered logical
message to be erased. (This identifier would have been determined using a
page query command.) If the message specified is security-protected, the operator
should have a security code that matches the one in the message.
If a message identifier (hhhhhh) is not specified in the termination request
and there is no message currently displayed, the oldest message is automatically
retrieved.
