TI DataEditor overview

Click TI DataEditor to create and work with data variables. TI DataEditor is a convenient way for you to manipulate numeric data stored on your personal computer (PC) instead of editing the data on your TI handheld device. It is not a program editor. Use TI DataEditor to work with List, Number, and Matrix variables created on your TI handheld devices. With TI DataEditor, you can create, display, and modify any of these variables.

Use TI DataEditor to:

Create data files (create Lists, create Numbers, create Matrices)

Open data files (open Lists, open Numbers, open Matrices)

Save data files (save Lists, save Numbers, save Matrices)

Close data files (close Lists, close Numbers, close Matrices)

Export data files (export Lists, export Numbers, export Matrices)

Import data files (import Lists, import Numbers, import Matrices)

Send data files to a device (send Lists, send Numbers, send Matrices)

Print data files (print Lists, print Numbers, print Matrices)

Change data file properties (change Lists, change Numbers, change Matrices)

Be sure to see Frequently-asked questions, TI DataEditor screen layout, Selecting a variable type, TI DataEditor status bar, and Navigation within TI DataEditor to learn more about using TI DataEditor.

See also TI DataEditor menu definitions.

Notes:

•	All numeric data for the TI-89, TI-92, TI-92 Plus, or Voyage 200 that is either saved by or sent to the device with TI DataEditor is converted to floating point format.

•	TI DataEditor lets you use your computer to manipulate variables whether the data is in a List, Number, or Matrix file. However, you cannot edit constant files from the TI-73 (xxx.73xc). To edit .73c files, use the Program Editor function of the TI-GRAPH LINK™ software.

List variables defined

Lists, as used in the TI handheld devices, are simply numeric data stored in a list format, single column, top to bottom. Lists can contain only single-dimension (one column) numeric data.

List data can be real or complex. However, not all devices support complex numbers. If you try to save a List containing complex numbers to a device that supports only real numbers, TI DataEditor displays a warning.

You can also create a data List with an ASCII text editor or with a spreadsheet program and then import it into TI DataEditor. Conversely, you can export lists into .csv (comma delimited) or .txt spreadsheet format.

With TI DataEditor, you can create and display as many Lists as your computer memory supports.

List names are not limited to L1 through L6. List names on the TI-73/83/83 Plus can have up to five characters or L1 through L6. List names for the TI-89/92/92 Plus/Voyage™ 200 devices can have up to eight characters but must start with a letter.

Why does my file have a different file name than what I gave it?

This occurs most often when you open an existing file, make some data changes, and then save it as the new file name. You notice your file name on the PC has the correct file name but when you open it, the file name shown in Edit mode is the same as the original file name.

When you create a new file from an existing file, the new file inherits the internal (variable) name from the original file. There is no way to change it. You must create a new file with both the file name and the variable name you want.

However, you can change the internal file name by using the Properties function of TI DataEditor.

Why can't I see my List when I click on File, Open?

When you attempt to open a file on your PC, TI DataEditor filters the type of files that display based on your default device and the viewing mode you selected in the Options window. For example, if you have aTI-89 connected to your PC and you are in the List view, TI DataEditor only displays valid TI-89 format files. To display more file types, in the Select File(s) to Open window, click All Calculator Files. You can also change your default device type and view mode to view files of different types.

How do I edit my Numbers?

To change a number, click that cell and start typing. What you enter replaces the current cell contents.

To edit and not replace the data in the cell you have selected, double-click the cell (or press F2) and then change just the characters you want to change. Press Enter to save your data.

Why can't I move my cursor around anymore?

This is most likely because you are still editing a cell. When you edit a cell, the arrow keys move within the cell and not around the rows and columns. The best thing to do is press Enter to complete the edit and then you should be able to move around again.

What kind of Numbers are valid?
What kinds of Numbers are valid?

TI DataEditor lets you enter numbers in several formats. You can enter the numbers 0 through 9. You can enter + or – at the front of the numbers. You can enter "e" or "E" for exponential format and you can enter a decimal point for floating point numbers. You cannot enter fractions with the "/" or any other algebraic symbols. You cannot have any spaces in your Numbers and you cannot use any other characters or variables in your Numbers.

How do I make a Complex Number
How do I make a Complex Number?

You can enter the real part of the number, then enter the complex part of the number, and then enter "i" or "I". For example, "3+4i" is a valid complex number. You cannot have any spaces in your numbers and you must have the "+" (or "-") between the real and the complex part. You must have the trailing "i" for the complex part. You can enter a complex number in a real List. However, since TI devices mark the entire list as Real or Complex, the entire List is converted to a complex List.

How do I set my default directory?

Click Tools > Options. Change the User Data field to be the directory you want as your default. From then on, all of the File > Open and File > Save windows start with that directory.

How can I quickly move a few cells from a List into Excel?

Open your List in TI DataEditor. Select the cells you want. Click Edit > Copy. Switch to Excel. Click Edit > Paste.

Can I copy/paste into TI DataEditor
Can I copy/paste into TI DataEditor?

Yes. Copy and Paste works as you would expect for both sending and receiving data.

Why do zero cells show up when I do a Cut?

Since a cell cannot truly be cut from a Number or a Matrix, the cell data is replaced with zero when you do a Cut operation. For a List, you can delete cells, but you must use the Edit > Delete operation.

© 2003 Texas Instruments Incorporated


How do Insert and Delete work?

Insert and Delete work only on Lists. You cannot add or delete cells on a Matrix or Number. Select the cell you want to insert or delete and click Edit > Insert or Edit > Delete. You cannot delete the last cell of a List.

While you cannot add or delete cells on a Matrix, you can change the number of rows and columns in a Matrix, which, in effect, adds or deletes cells. Click File > Properties to change the Matrix.

© 2003 Texas Instruments Incorporated


How do I change the size of my Matrix?

Change the Matrix size by changing the Matrix properties. Click File > Properties and change the size of the Matrix. If you are making the Matrix smaller, you may lose data, so be careful.

What types of variables are supported?

TI DataEditor supports real and complex Numbers, Lists, and Matrices. No other types are supported. Remember, not all combinations of these variables are supported by all TI devices.

© 2003 Texas Instruments Incorporated


What variable names are legal?

The variable name is set when you display the file from the TI device or the PC file. If you create a new variable, you must select the device type before you enter a variable name. In all cases, TI DataEditor checks the variable name to make sure it is legal on the device the variable is intended to be sent to.

For example, while many devices support Greek characters as part of the file name, TI DataEditor does not. However, if you use Greek characters in the file name on your device, you can copy the file to your PC using TI DeviceExplorer, make any data changes you want with TI DataEditor, and then copy the same file back to your device. You just cannot create file names with TI DataEditor that contains Greek characters.

What's the difference between Import/Export and Open/Save?

Import and Export work with file formats called .txt (ASCII text) and .csv (comma delimited). These are file formats that are commonly used to exchange data with word processors and with Excel. You will lose some information (such as the variable name) when you export a variable, but you will not lose your data.

Why was my number with 25 digits of accuracy rounded off when I sent it to the device?
Why was my number rounded off when I sent it to the device?

Version 1.2 of TI DataEditor does not support the Fixed Point (Integer) format for numbers that the TI-89/92/92 Plus/Voyage™ 200 supports. Therefore, all numbers within TI DataEditor are floating point numbers. In some cases, this can result in a small loss of precision if the magnitude of the data is very large and there are more than six significant digits in the data.

© 2003 Texas Instruments Incorporated


Why do my numbers display as 1.#inf?

Numbers on your TI-89/92/92 Plus/Voyage™ 200 device that display as 1.#inf in TI DataEditor are the result of math performed on the internal PC number system. This number system is less accurate and has less dynamic range than the system on the TI-89/92/92 Plus/Voyage 200. Therefore, numbers where the magnitude of the exponent is larger than about 307 cannot be represented properly on the PC and are shown as zero (for very small numbers) and 1.#inf (for very large numbers).

© 2003 Texas Instruments Incorporated


Why can't I see all the data in my big list?

TI DataEditor handles lists of up to 10,000 elements, enough to support the largest lists on every TI handheld device. However, to improve performance on slower computers running TI DataEditor, the default size is set to 1,000 elements. If you have lists with more than 1000 elements, click View > Enable Large Lists. If you do not select Enable Large Lists, you do not loose any data, but you cannot see or edit some of the data.

Navigation within TI DataEditor

Generally, navigation within TI DataEditor is as you expect. The arrow keys move you from cell to cell and clicking on a cell moves you to that cell. TI DataEditor uses two navigation techniques called Focus and Selection.

Focus

Focus is the place where any typing that you do is entered. The cell with the focus has a rectangular box around it, making the cell stand out slightly.

For the Properties command, TI DataEditor only changes the item with the focus. If no item has the focus, then the command is not processed.

Click a cell with the left mouse button to change the focus. Click with the right mouse button to change the focus and display a context menu of commands.

Selection

Selected cells are colored with a blue background. If you are going to perform an action (like saving a list), the action is performed only on variables where there is a cell selected.

Change selection by clicking a cell. If you click a cell, all previous items are unselected and the clicked cell is selected. To add a cell to the selection, press and hold Ctrl and click the cell to be added. To select a range of cells, press and hold Shift and click the first cell in the range then click the last cell in the range. If you click the column/row headers, the selection is reset to that column/row.

When trying to figure out what you want TI DataEditor to do for the Save and Close commands, TI DataEditor first looks to see what cells are selected and performs your command on the variables with selected cells. If there are no items with selected cells, TI DataEditor tries to perform the action you want on the variable with the focus. If there are still no items to process and there is only one item displayed, TI DataEditor tries to perform your action on that item.

When selecting the context menu by right-clicking a cell, if there are cells selected on another variable, those variables are processed, not the one that you have right-clicked. If there are no cells selected, then the item processed is the one with the focus – the one you right-clicked. So, if you want to be sure to process only the item you right-click, left-click that item first (to unselect any other selected cells) then right-click and select a command. To select several variables and process them all, after selecting cells in any items you want to process, right-click and then select your command.
