If an INPUT# statement attempts to read beyond the end of a disk
file, an error will result.
The GET statement is used to read a single numeric value via the
opel"] channel specified . GET uses the following configuration:
GET #channe/, numeric variable
The
channel
specified must be open for input. The numeric
variable indicated will accept the value returned by GET. This
value will lie between 0 and 255.
When GET is used with the 810 Disk Drive and the buffer is
empty, the initial GET statement will result in a block of data
being read into the disk buffer. The first value in the buffer will
be assigned to the numeric variable specified with the first GET
statement.
Each successive GET statement will read a value from the buffer.
When the buffer has been emptied , another block of data will be
read into the buffer from the diskette.
NOTE and POINT
NOTE and POINT are BASIC statements that aid the user in
random access of Atari disk files . Random access is only possible
with DOS version 2.0.
The NOTE statement will return the position of the file pointer.
The file pointer will be referenced using two separate data items.
One data item is the number of the last sector accessed. The
other data item is the number of the last character referenced
within that sector.
The NOTE statement uses the following configuration:
NOTE
#channe/ , sector, character
The NOTE statement will reference the file opened with the

number. The number of the last sector
accessed will be assigned to the variable given in
sector.
