is, optionally, the length of the record in bytes (default 128
bytes).
Remarks An OPEN statement must be executed before a file or device can be used
for input, output, and/or append. A maximum of 25 files and/or devices
can be open at the same time.
Sequential Access Mode
The access mode can optionally be specified as sequential INPUT,
OUTPUT, or APPEND:
INPUT Sequential input from the file/device, replacing existing data.
Existing files/devices only.
OUTPUT Sequential output to the file/device, replacing existing data.
APPEND Sequential output to the file/device, where new data will be
appended without replacing existing data.
Random Access Mode
If no access mode is specified in the statement, the file/device is opened
for both input and output (RANDOM access mode). FIELD, LSET,
RSET, PUT, and GET can only be used on records in files OPENed in the
RANDOM access mode.
Please refer to the DEVICES statement for information on which devices
can be opened for the different modes of access.
Lists of the files stored in the various parts of your printer’s memory can be
obtained by the use of the FILES statements.
