1
Operand information relating to whatever operation is being performed. (must be
integer)
2
Additional information about the operation to be performed.
3
The Calculator Type specifies the model of the calculator on which the user program
is running. This determines which programs in the CBL 2 archive will be shown in the
directory information. Available choices are: 73, 82, 83, 83.1 (for 83 Plus), 86, 89, 92,
and 92.1 (for 92 Plus).
4
The Directory Type specifies the entries in the archive on which to perform the
operation. Available choices are: 0 (Sample Data Set), 1 (Saved List), and 2 (Saved
Program).
5
If a directory entry does not have a label assigned to it, the CBL 2 reports the label as
'????????????????????'.
5,6
Because the TI-82, TI-89, TI-92, and TI-92 Plus do not receive string variables, the
program names in the directory cannot be passed directly as strings. The Numeric List
option in operation 3 provides an indirect way of representing the names. The list
contains the ASCII code for each character in the name. These ASCII codes can be
interpreted by the user program to display the correct letters on the calculator.
6
Send a command with Operation 4 to set up label directory entry; then follow it with
another command that contains the label.
7
Built-in user programs: The CBL 2 stores a collection of calculator programs
(DataMate) and look-up tables in its FLASH memory. These programs are intended to
simplify the task of data collection and analysis. Because these programs are designed
to work together, they can only be stored and deleted as a group. To free up memory
in the CBL 2, you can delete the programs for calculators that you do not use.
Upgrading User Programs: The FLASH Download software provides a way to update
the user programs and lookup tables for all calculator platforms. The FLASH Download
process automatically deletes all existing user programs (all calculator models) from the
archive. The new look-up tables and programs are then installed into the archive.
(Instructions for downloading new software are given on the TI web site at
www.ti.com/calc.)
8
Two optional identifying numbers can be used when saving a data set or list. These
numbers are saved with the data in addition to the supplied label.
9
Operations 24, 25, and 26 are provided to facilitate saving configuration information
in the same data structure as a saved experiment, rather than in a separate file.
10
Operation 41 allows you to retrieve programs saved on the CBL 2. You can save
programs to the CBL 2 by enabling writing {201,0,0,0,2.46802} and then sending
programs from the calculator's LINK/SEND menu.
11
Operation 42 cancels operation 41 or 43. If the TRANSFER key is not pressed within
one minute, operations 41 and 43 cancel automatically.
