About ASCII List Files

You can import a  list from an ASCII list file into a TI-GRAPH LINK file on the PC. You can then send the file to the TI-83 Plus.

Before importing an ASCII list file, you should be aware of the guidelines for numerical and complex numerical lists shown below.

Numerical Lists

•	The numbers that make up the list can be in standard or scientific notation (such as 1.23E15), and can be separated by any of the following characters:

-	comma	-	line feed

-	carriage return	-	tab

•	If parentheses ( ), brackets [ ], or braces { } are included with the data, an error message is displayed.

Complex Numerical Lists

The input for complex numerical lists is the same as above but in complex number format a + bi.

Matrices
Matrix Examples

Data is read into the matrix row by row. Reading stops when the matrix is full. If the data file does not contain enough elements for the matrix, TI-GRAPH LINK attempts to fill the empty cells with zeros.

Example:

Both of the following files produce the same 9-element matrix if read into a 3-by-3 real matrix. TI-GRAPH LINK ignores the extra two elements (17,28) at the end of ASCII File 3.

ASCII File 3	ASCII File 4

-45,45,0,30,0,40	-45   45    0

-2,-13,-5,17,28	 30    0   40

 -2  -13   -5

Questions
Problems and Solutions, and Frequently Asked Questions

Q:	Many special characters, such as Greek characters, in the TI-83 Plus Function List selection window are incorrect.

A:	TrueType fonts are not enabled

1.	For Windows 3.1x, open the Windows Control Panel, Fonts, TrueType option and make sure the "Enable TrueType Fonts" box is selected.

2.	For Windows 95, make sure that the custom TI-83 Plus font files are in the \Windows\Fonts directory.

Q:	The error message "Transmission Error" is displayed when attempting to send or receive from a TI-83 Plus.

A:	This error can be caused by any of the following:

1.	TI-GRAPH LINK cable not plugged in firmly (at either end).

2.	The selected cable type (Black/Gray cable) is different from the actual cable in use.

3.	Com port selected is not the Com port to which the calculator is connected.

4.	The calculator may have been placed in Link/Receive mode -- it should be on the Home screen.

5.	A Send or Receive operation was stopped before the operation was completed.

Q:	The error message "Cannot open the communication port" is displayed.

A:	The serial port that you selected from the Link menu may be in use by another device. For example, you selected Com Port 1 and your mouse is also connected to this serial port. Select another serial port from the Link menu and try again.

A:	The Com Port selected may not be correct. Ensure that the selected port is the one in which the TI-GRAPH LINK cable is connected.

Q:	The error message "Invalid file name" is displayed.

A:	You tried to save a file starting with an invalid character such as a number or Greek character. Although numbers are valid in DOS file names, the TI-83 Plus requires file names to begin with a character.

Q:	The error message "Unrecognized file type" is displayed.

A:	You tried to open an invalid file type such as an application variable.

Q:	Can TI-83 file types (.83) be sent to a TI-83 Plus calculator?

A:	Yes. TI-83 files are automatically converted and renamed to TI-83 Plus format.

Q:	What TI-83 Plus file types cannot be sent to a TI-83 calculator?

A:	Although most TI-83 Plus files can be sent to a TI-83 calculator, some data types, such as AppVars, Apps, and Program files that include new tokens (e.g., Archive, UnArchive, etc.) will not be recognized on the TI-83. Additionally, application variables (*.8xv) and ASM-compiled programs cannot be sent to the calculator, nor can they be opened, edited, or printed.
