FRE

Field of Application

Function returning the number of free bytes in spciﬁ ed part of the

printer’s memory.

Syntax FRE(<<sexp>|<nexp>>)

<sexp> is the designation of the part of the printer’s memory from

which the number of free bytes should be returned, for

example "c:", "tmp:", "card1:".

<nexp> is a dummy argument. Returns the number of free bytes in

the printer’s temporary memory ("tmp:").

Remarks

The ﬁ rmware 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 speciﬁ es device "card1:", but no card is inserted, Error

1039, “Not mounted" will occur.

If the name of a device, that is not a part of the printer’s memory (for

example "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 (for

example "QWERTY:"), Error 1013, “Device not found” will occur.

Any argument, that does not include a colon sign (for example “7”

or "QWERTY”), will return the amount of free bytes in the printer’s

temporary memory ("tmp:").

Example

PRINT FRE("tmp:")

yields for example:

2382384

PRINT FRE("uart1:")

yields:

PRINT FRE(1)

yields for example:

2382384

1 2 ... 100 101 102 103 104 105 106 107 108 109 110 ... 331 332
