AM3270 Management Programming Manual
 ELEMENTS OF SPI MESSAGES FOR THE SUBSYSTEMS
 Tokens
 ZSPI-TYP-FNAME ZSPI-TYP-TIMESTAMP
 ZSPI-TYP-FNAME32 ZSPI-TYP-TOKENCODE
 ZSPI-TYP-UINT
 The AM3270 subsystem does not define any private token types;
 that is, no token types have names of the form ZAM3-TYP-
name
.
 Predefined Value Names
 The predefined values used by the AM3270 subsystem are repre-
 sented by symbolic names Z
subsys
-VAL-
name
, where 
subsys
 is a
 three-character subsystem abbreviation and 
name
 identifies the
 predefined value. For example, the predefined value ZAM3-VAL-
 SSID represents the subsystem ID of the AM3270 subsystem that
 is present in all commands and responses associated with the
 AM3270 subsystem. The predefined value names used by the AM3270
 subsystem are as follows:
 ZAM3-VAL-BUFLEN ZAM3-VAL-VERSION
 ZAM3-VAL-EVT-BUFLEN ZSPI-VAL-FALSE
 ZAM3-VAL-MAXBUFLEN ZSPI-VAL-TANDEM
 ZAM3-VAL-SSID ZSPI-VAL-TRUE
 For descriptions of these predefined value names, see the
 subsection "Predefined Token and Field Values" in Section 5,
 "Common Definitions"
 Field Types
 The field types used by the AM3270 subsystem are represented
 by symbolic names of the form Z
subsys
-DDL-
name
, where 
subsys
 is a three-character subsystem abbreviation and 
name
 identifies
 the field type. For example, the field type ZSPI-DDL-BOOLEAN
 represents the Boolean data type. Some field types are defined
 by SPI; others are private field types defined by the subsystem.
 The field types that can be used by the AM3270 subsystem are as
 follows:
 ZSPI-DDL-BOOLEAN ZSPI-DDL-FNAME32
 ZSPI-DDL-BYTE ZSPI-DDL-INT
 ZSPI-DDL-CHAR ZSPI-DDL-INT-PAIR
 ZSPI-DDL-CHAR6 ZSPI-DDL-INT2
 ZSPI-DDL-CHAR8 ZSPI-DDL-INT4
 ZSPI-DDL-CRTPID ZSPI-DDL-TIMESTAMP
 ZSPI-DDL-ENUM ZSPI-DDL-UINT
 ZSPI-DDL-FNAME
