Device Search Order
If you are using the PostScript emulation operators
run, file, renamefile, status
or
eexec
, you do not need to specify the device. If you omit the device name, devices
are searched in the default order: disk and then flash memory. If the following
PostScript emulation code is encountered,
(myfile) (w) file
the file on disk is used (since disk occurs before flash memory in the default search
order), and files cannot be created in ROM.
The operator
deletefile
searches only the first device in the default search order if a
device is not specified.
Use the PostScript emulation operators
devmount
,
devdismount
to change the
order. The default search order is determined by the order the devices are mounted.
For example, if you want to place the disk device after the flash memory in the default
search order, use the following command sequence:
(%disk%) devdismount
(%disk%) devmount
To change the order so the devices are searched as disk, flash memory, and then
ROM, use the following PostScript emulation command sequence:
(%rom%) devdismount
(%flash%) devdismount
(%disk%) devdismount
(%disk%) devmount
(%flash%) devmount
(%rom%) devmount
If the device is already mounted, the following operators may change the search
order:
•
initializedisk
•
devformat
•
<</InitializeAction>>setdevparams
Sending these operators has the following effect on the devices in the search order:
1
If mounted,
(%device%)
devdismount
2
Formats the device
3
If dismounted in step 1, (
%device%
) devmount
