AM3270 Management Programming Manual
 SECTION 6
 COMMANDS AND RESPONSES
 This section describes each of the commands and responses in the
 programmatic command interface to the AM3270 subsystem. Each
 description includes the syntax, object types, command tokens,
 response tokens, operational notes, and error handling associated
 with the commands.
 In this section, command numbers, object types, tokens, and token
 values are represented in DDL. For a quick explanation of DDL
 as it applies to SPI, refer to the appendix "Overview of DDL
 for SPI" in the 
Distributed Systems Management (DSM) Programming
Manual
 The commands available in the programmatic interface allow an
 application to do the following:
 • Change the attributes of AM3270 objects
 • Start and stop the operation of AM3270 objects
 • Add a subdevice to or remove a subdevice from the AM3270
 subsystem
 • Obtain attribute values
 • Obtain statistical and status information
 • Obtain information about the object names known to the AM3270
 subsystem
 • Trace the activity of an AM3270 line
 • Change the system resources used by an AM3270 process or line
