PostScript emulation 120 Key Type Definition InitializeAction integer Specifies an action for initializing the flash memory. Supported values are: • 0-Indicates no action. The value returned when the parameter is read. • 1-Indicates that the current file system should be deleted and a new one of PhysicalSize created (the flash memory must be formatted already). The flash memory must first be mounted; otherwise, an ioerror occurs. • 2-Reformats the entire flash memory before creating a file system of PhysicalSize. • 3 (or greater)-Has the same effect as the value 2 and also tests the flash memory x‑2 times. Legal value: Any non‑negative integer. LogicalSize integer This parameter is not used for InitializeAction. InitializeAction always formats to PhysicalSize, regardless of what is specified in LogicalSize. A query returns the current size (in pages) of the file system on the device. A value of 0 indicates that the device is not mounted. Legal values: Any non‑negative integer, including 0. The value of LogicalSize must be less than equal to the value of PhysicalSize. If set to a value greater that PhysicalSize, or less than zero, then a rangecheck error occurs. Mounted Boolean A device must contain a valid file system to mount successfully. When a device is mounted, it is known to the system and is readable. To verify if the device is mounted, query this parameter immediately after setting it. Supported values are: • True-System attempts to mount the flash memory. • False-System attempts to dismount the flash memory. PhysicalSize integer (Read‑only) Indicates the size of the flash memory (in pages). Valid only when the flash memory is mounted. A value of 0 indicates that the device is not mounted. Removable Searchable Boolean Boolean (Read‑only) Indicates that the drive supports removable flash memory. (Read‑only) Indicates that a flash memory participates in searches in file system operations that specify a file name without specifying a device. SearchOrder integer (Read‑only) If the Searchable parameter is True, then the value indicates the priority at which the flash memory is searched for a file in operations where no device is specified. A lower integer indicates a high priority. If the Searchable parameter is False, then the value of this integer has no meaning. Type Writeable name Boolean (Read‑only) Always returns the value of /FileSystem. (Read‑only) Indicates that the files on the flash memory can be opened for write access. A write‑protected flash memory returns False. When the flash is not mounted, this parameter indicates that the device supports writeable media. Device Parameters for the Parameters Device %rom% BlockSize integer (Read‑only).

Key
Type
Definition
InitializeAction
integer
Specifies an action for initializing the flash memory.
Supported values are:
•
0—Indicates no action. The value returned when the parameter is read.
•
1—Indicates that the current file system should be deleted and a new
one of PhysicalSize created (the flash memory must be formatted
already). The flash memory must first be mounted; otherwise, an
ioerror
occurs.
•
2—Reformats the entire flash memory before creating a file system of
PhysicalSize.
•
3 (or greater)—Has the same effect as the value 2 and also tests the
flash memory x
‑
2 times.
Legal value: Any non
‑
negative integer.
LogicalSize
integer
This parameter is not used for InitializeAction. InitializeAction always
formats to PhysicalSize, regardless of what is specified in LogicalSize. A
query returns the current size (in pages) of the file system on the device.
A value of 0 indicates that the device is not mounted.
Legal values: Any non
‑
negative integer, including 0. The value of
LogicalSize must be less than equal to the value of PhysicalSize. If set to
a value greater that PhysicalSize, or less than zero, then a
rangecheck
error occurs.
Mounted
Boolean
A device must contain a valid file system to mount successfully. When a
device is mounted, it is known to the system and is readable. To verify if
the device is mounted, query this parameter immediately after setting it.
Supported values are:
•
True—System attempts to mount the flash memory.
•
False—System attempts to dismount the flash memory.
PhysicalSize
integer
(Read
‑
only) Indicates the size of the flash memory (in pages). Valid only
when the flash memory is mounted. A value of 0 indicates that the device
is not mounted.
Removable
Boolean
(Read
‑
only) Indicates that the drive supports removable flash memory.
Searchable
Boolean
(Read
‑
only) Indicates that a flash memory participates in searches in file
system operations that specify a file name without specifying a device.
SearchOrder
integer
(Read
‑
only) If the Searchable parameter is True, then the value indicates
the priority at which the flash memory is searched for a file in operations
where no device is specified. A lower integer indicates a high priority. If
the Searchable parameter is False, then the value of this integer has no
meaning.
Type
name
(Read
‑
only) Always returns the value of /FileSystem.
Writeable
Boolean
(Read
‑
only) Indicates that the files on the flash memory can be opened for
write access. A write
‑
protected flash memory returns False. When the
flash is not mounted, this parameter indicates that the device supports
writeable media.
Device Parameters for the Parameters Device %rom%
