remote MTA
remote MTA. An adjacent or nonadjacent MTA. Any MTA other than your local OSI/MHS 
subsystem.
Remote Operations Service. See ROSE.
remote system. In Compaq terms, any system within an Expand network that is not the local 
system.
remote user agent. See RUA.
report. A notification generated by the OSI/MHS subsystem that tells the user whether the 
message has been sent.
request primitive. In OSI, a primitive issued when a service user wants the service to do 
some work. This is one of four types of service primitives. See also service primitive.
reserved object. An object on the input queue that the client program has started transferring 
in and to which the GPI has assigned an object identifier. A client program can examine 
or copy a reserved object (and its attributes) but not modify it.
response. In OSI, see response primitive.
In DSM, the information or confirmation supplied (as part of a response message) to an 
application by a subsystem in reaction to a DSM command.
response message. An SPI message sent from a subsystem to an application program in 
reaction to a command message.  See also command message or event message.
response primitive. In OSI, a primitive issued when a service user wants to respond to an 
event. This is one of the four types of service primitives and is used only for confirmed 
services. See also service primitive.
response record. In DSM programmatic interfaces, a set of response tokens, usually 
describing the results of performing a command on one object. Every response record in 
a response from a Compaq subsystem contains a return token; a response record can also 
contain error lists that include error tokens.  A response can consist of multiple response 
records, spread across one or more response messages.
result file. In the P7 API, a file used for retrieving results from the OSI/MHS subsystem. The 
file number is returned by a call to the LOS_OPEN_ procedure.  See also send file.
return token. In DSM programmatic interfaces, the token that indicates whether a command 
was successful and, if not, why it failed.  The token code for the return token is 
ZSPI TKN-RETCODE. Its value consists of a single integer field. See also error token.
root object. In the GPI, a message, probe, report, or P1-encoded object.
