Lexmark X644e User Guide

For any PostScript emulation operator that requires a filename parameter, the 
filename can be one of the following:

%device%filename

Specifically references a file on a particular device. If the filename does not exist 
on %device%, no other %device% is accessed for a duplicate filename.

filename

Does not specifically reference a device. The following action occurs:

•

For the PostScript emulation operator deletefile, only the first device in the 
search order is checked for filename.

•

For all other PostScript emulation operators, and all other combinations of 
search order and available devices, each installed %device% is checked in 
the search order for the existence of filename. The operator acts upon the first 
filename that it finds.

The term device refers to flash memory, disk, or ROM. For PostScript emulation, some 
of the operators require or return device names. These operators are: deletefile, 
filenameforall, devforall, devdismount, devmount, devformat, devstatus. The 
device always begins and optionally ends with a % character. The following are the 
valid device names:

%rom%

%flash%

%flash1%

%disk%

%disk1%

The same filename can exist on more than one device. The device prefix determines 
the actual file to use. For example, 

and

designate, 

respectively, a file called

 myfile

 both on the ROM and on flash memory. The device 

name distinguishes which file to use.
