kManual Conventions
•The terms “Program-Link” and “this software” as used in this manual refer to the
Program-Link software that comes with the FA-123 Package.
•The term “calculator” as used in this manual refers to your CASIO Graphic Scientific
Calculator.
•This manual explains only the procedures required to operate the Program-Link
application software. It assumes that you are already familiar with the following
computer operations.
•Pull-down menu operations, clicking, double-clicking, and dragging with the
mouse
• Text input using the keyboard
• Icon and window operations.
See the documentation that comes with your computer for full details on these
operations.
• All of the operations in this manual are explained using the Windows operating
system. What actually appears on the display of your computer may differ some-
what if you are using a different operating system.
• Menu operations are notated within the text of this manual as hyphenated com-
mands with the menu hierarchy progressing from left to right.
Example Selecting the Open command from the File menu would be
described as: “Select File-Open .”
Menu (Windows)

uText files
This type of file consists of two parts: a group and the multiple items stored under it.
Except for graphic data, all items can be displayed on a computer screen, and pro-
grams can be edited on the computer.
Text Files
uBack-up file
This file contains the data produced when you back up all of the data in calculator
memory.
uGraphic files
This type of file contains the data produced when you use the screen capture func-
tion to create a bit pattern of the screen and save the bit pattern to your computer.
Graphic data is saved using one of the two following file formats.
• Windows: Bitmap
• Macintosh: PICT
Graphic data can also be converted to one of the following file formats.
• Windows: TIFF, PCX
• Macintosh: TIFF
• Graphic files saved as one of the above file formats cannot be opened using
Program-Link.
