FRE
Chapter 2 Program Instructions
Field of Application Function returning the number of free bytes in spcified part of the
printer's memory.
Syntax FRE()
is the designation of the part of the printer's memory from
which the number of free bytes should be returned, e.g. "c:",
"tmp:", "card1:".
is a dummy argument. Returns the number of free bytes in
the printer's temporary memory ("tmp:").
Remarks The firmware looks for a colon (:) sign in the argument for the FRE function.
If the argument is valid name of a memory device, the number of free bytes
in that device is returned.
If the argument specifies device “card1:", but no card is inserted, error
condition #1039 “Not mounted” will occur.
If the name of a device, that is not a part of the printer's memory (e.g. "uart1:"
or "console:"), is entered as an argument, the FRE function will return 0.
Refer to DEVICES for more information on memory and non-memory
devices.
If the argument contains a colon, but is not a valid name of any device (e.g.
"QWERTY:"), error condition #1013 “Device not found” will occur.
Any argument, that does not include a colon sign (e.g. 7 or "QWERTY"), will
return the amount of free bytes in the printer's temporary memory ("tmp:").
