Naming Conventions
Naming Conventions
SPI data definitions have names of this form.
subsys
is a four-character abbreviation that identifies the subsystem that defined the item.
Some subsystems declare many of their own definitions in addition to the common
definitions that are used by most subsystems (such as those defined by SPI and
EMS). All
subsys abbreviations beginning with an uppercase or lowercase Z are
reserved for HP definitions. Some examples of
subsys abbreviations are:
type
is a three-character mnemonic that indicates the type of data object that the name
represents: a value, object type, or command, for example. The most commonly
used mnemonics and the types they represent are:
subsys-type-description (in DDL and COBOL)
subsys^type^description (in TAL and TACL)
subsys_type_description (in C)
