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
If you do not want a device searched, dismount it and leave it dismounted.
