Description
accesstype
ACCESS =
accesstype
One of the following access types must be specified when a file is opened:
RO
Open for read only. The file must already exist on the specified
device.
WO
Create a new file. If the file already exists, its contents will be
discarded and a new file will be created.
RW
Open for reading and writing. The file must already exist.
AP
Open for reading and writing, and position the file pointer to the end
of the file. The file must already exist.
Access types are case sensitive.
The LREADFILE command is ignored if the file was not opened with an
accesstype
of
RO
,
RW
, or
AP
. The LWRITEFILE command is ignored if the
file was not opened with an
accesstype
of
WO
,
RW
, or
AP
.
bytecount
LENGTH =
bytecount
The amount of data in bytes to be read or written. The parameter is optional
for both the LREADFILE and LWRITEFILE commands.
If the LENGTH parameter is omitted from the LREADFILE command,
bytecount
is assumed to be equal to the entire file beginning at the START
location. If the LENGTH parameter is omitted from the LWRITEFILE
command, an @PJL END DATA command must be placed at the
end
of the
data. All data up to ‘@’ in @PJL END DATA is written to the file.
Note:
The LWRITEFILE command requires that
either
the LENGTH
parameter or the @PJL END DATA command be specified, but not both.
If the LENGTH is greater than the file size on a LREADFILE command, it is
assumed to be the entire file beginning at the START location.
