Writing a File Externally


The procedure on this and the following pages describes how to write (store) a file externally. You can write either a program file or a data file.


Initial Steps

To begin writing a file externally:
  1. Press [ I/O ] { Pad } to display the iPad STORAGE menu.
  2. Select { WRT } from the menu.
    The calculator displays:
    D_TNEsTN
  3. Press the applicable key for the type of file you want to save.
  • For a program file, press { PGM } and proceed to the instructions for "Entering the File Name" below.
  • For a data file, press { REG } and proceed to the instructions below.

If the File is a Data File…

If you selected { REG }, the calculator displays:
D_mUq7vr

  1. Specify both the number of registers to be written and the address of the first register by entering a number. The number must be of the form:

    nnn.sss

    where nnn specifies the number of registers, and sss specifies the starting register. You must include leading zeros in sss. If you do not specify sss, the calculator assumes the starting register to be 000.
  2. Press { ENT } to enter the number.

The calculator then prompts you to enter the name of the file.

Entering the File Name

After you specify the type of file (and, in necessary, the data registers to be written), the calculator displays:
D_BbbA8E
  1. Enter a three-character name for the file. (If you specified a data file, a + is automatically displayed as the first character in the name.)
  2. Press { ENT }.

The calculator then prompts you to press OK to write the file.

Saving the File

The following sequence of prompts are displayed when you are saving a file to external storage (there may also be a screen that displays "Writing..." if the program or data being saved is large.)

D_DpVRMKPrepare to save the file.

D_CHoZojSave the file

D_RAPiooFinished saving the file

D_QCWDfvConfirms the file has been saved.

Note:

There are several prompts to press OK... during an external file writing operation. This is due to the original design of the external file operations in the original calculator from which this application is derived, where external file operations were performed using a cassette tape recorder.

Anytime an external file operations menu contains the { ESC } selection, you can press { ESC } to cancel the operation.
