Table 3-22: Variables for Flash and Disk File and Password Commands (Continued)

Parameter	Syntax	Description
location	START = location	The location in the file to begin writing or reading. Use an integer that
		represents an offset in bytes from the beginning of the file.
		Optional for both LREADFILE and LWRITEFILE commands. If omitted on an
		LREADFILE command, location of 0 (beginning of the file) is assumed. If
		omitted on an LWRITEFILE command with an accesstype of RW,
		location of 0 is also assumed.
		If a START location is provided but it is greater than the file size, the
		LREADFILE command response will contain no file data. Similarly, an
		LWRITEFILE command with an accesstype of RW functions like an
		LWRITEFILE command with an accesstype of AP.

Note: If PostScript emulation is used to create the file on the device, it may automatically attach a .data extension to the fname. See “Filename Extensions” on page 6-10for more information. For example, if downloaded to flash through PostScript emulation, the fname on the PJL commands is "myfile.data".
