Declaring a Simple Data Item
an even number of bytes. In this case, either all occurrences of the
substructure are word-aligned or none are.
Declaring a Simple Data Item
A simple data item declaration associates an identifier with a single-element data item.
The syntax for a simple data item declaration is:
type identifier [ VALUE initial-value ] ;
type
is one of these data types:
BOOL
is a 16-bit signed value that is either true (represented by -1) or false
(represented by 0).
BYTE
is an 8-bit unsigned binary integer; its value is in the range 0 to 255.
CHAR
is an 8-bit ASCII character.
CRTPID
is a 4-word internal-format process ID.
DEVICE
is a 4-word internal-format device name.
ENUM
is a 16-bit signed, enumerated value whose range is defined by the subsystem
and depends on the token number; its value is in the range -32768 to +32767,
and its format is the same as for INT type.
FNAME
is a 12-word internal-format file name for a disk file, process, or device, in the
same form as that produced by the FNAMEEXPAND procedure.
