Description Use this command to retrieve a message from one or more exchanges.
It returns the first message in each target message queue.
Syntax Below is usage and syntax information for this command
Command Format rx (xid | name)
Variables None
Parameters xid = pSOS exchange ID (in hexadecimal); make an
attempt to retrieve a message from a single
exchange.
name = case-sensitive exchange name. The monitor
supports the new exchange naming convention.
If you enter an entire name, the monitor retrieves
the message from that exchange.
If you enter the first few characters, the
command attempts pattern matching. The
monitor retrieves messages from one or more
exchanges, depending on the number of matches.
Example Type rx 304540 and press ENTER.
This requests a message from the exchange with an ID of
304540.
Results: The message is displayed as six long, hexadecimal
words as:
A999 : 00000001 00000002 00000003 00000004
The system displays the specified message, then
returns to the prompt unless it encounters an error. If
this is the case, it displays an error message before it
returns to the prompt.
Special
Considerations
You must only use this command in a testing or debugging
context. If you take a message from an exchange
indiscriminately, you cannot predict the results.
