IF FILEFREE = 0 THEN GOTO X
Example for request FILEFREE
EOF
EOF contains the boolean value if the last position of a previously created data file is reached when reading.
EOF is true (-1) if end of file is reached or false (0) if not
In principle it is a compare of the current datapointer and the the saved pointer (done with CLOSE#)

EEPROM.WRITE
EEPROM.APPEND
EEPROM.READ
Moving just few bytes to the EEPROM there is an shorter option available, which manages file close and
open automatically in background.

Syntax: EEPROM.Instruction [parameter, ]
Parameter: word/byte variable or constant
LOOKTAB
TABLE
A Data File sometimes may be requested as read only (e.q converting sensor values by a table). The
required set of bytes can be allocated to a table. The Table is embedded in the compiler generated token
code and therefore read only. The internal data storage format for table values is always word format
The LOOKTAB instruction reads a word from a table. Looktab may either be used as function or as
instruction.
LOOKTAB MyTab,MyIndex,MyWord
TABLE myTab
0 1 2 3 4 5 6 7
END TABLE
0 1 2 3 4 5 6 7
END TABLE
Syntax: Looktab(Table, Index, Variable)
Variable = Looktab(Table, Index)
Index: word/byte variable or constant
Variable: word/byte variable
CHIPRAM
Chipram offers easy direct addressed access to Microchip I²C-Bus EEPROMs connected external to the
Ports 9 and 10. Please see Chapter DEDICATED DIGITAL PORTS. Applicable are EEPROMS up to 64
kByte capacity.
Syntax: CHIPRAM(address)
Address: word/byte variable or constant
Myword=CHIPRAM(MyAddress)
Example for reading a value
CHIPRAM(MyAddress)=MyWord
Example for writing a value
