── ? ── AT ──<host name>─┬────────────────────────────┬─<text>─────────┤ └─ [ ─┬─ HOSTSERVICES ─┬─ ] ─┘ └─ HS ───────────┘
Explanation
The ?AT command directs information to a remote host identified by the host name. The remote host interprets the text as an operator input message. After information has been sent to a remote host, a reply from the remote host is received with the following heading:
***REPLY FROM <host name>***
If the local host name is used in the ?AT command, the following text is displayed:
<host name> IS YOUR LOCAL HOST
The message can then be resubmitted without the AT <host name> prefix. Chaining of messages is not allowed, as shown in the following example:
?AT BLUE AT YELLOW WM
Example
The following example shows the ?AT command syntax:
?AT BLUE [HOSTSERVICES] J *** REPLY FROM BLUE *** ---Mix-Pri------------------ JOB ENTRIES --------------------- 1810 50 JOB (TESTUSER) TEST 1811 50 W ..(TESTUSER) *SYSTEM/CARDLINE
In the following example, the system does not respond after the FA TITLE command executes:
?AT BLUE 1568 FA TITLE=A ON DISK *** REPLY FROM BLUE *** NO RESPONSE GENERATED
