USING FORMAT FILES (continued)

As with all print commands, each line in a format file and

its accompanying variables must be terminated with the

carriage-return and line-feed character sequence.

Once defined, a format will remain in the printer's non-

volatile memory for future reference.  An existing format

can be changed by over writing the file.  By using the

DEL command, the format file can be deleted.

Format file names can consist of no more than 8 letters

or digits, and format file extensions can be no more than

3 letters or digits.  Any lowercase letter in the format file

name or extension will be converted to upper case.

Note: Every time a file is created on the printer using the

"! DEFINE-FORMAT...", "! DF..." or the Visual

Label Utility application, for example, the file

information is written to flash memory.  Unlike

RAM, flash memory does not require battery for

retaining data, and is immune to data corruption

due to static discharge.  Although flash memory is

superior to RAM for safe-guarding file contents, it

is limited to an average of 10,000 write cycles (i.e.

file creations).  For this reason, the user should

exercise the file creation commands such that the

stated limit is not exceeded.
