Storing and Recalling Alpha Messages

You can easily redisplay an alpha message that has been erased by a numeric value. However, to reuse a message that has been replaced by another alpha message, you must either reenter the original message or store the original message in data registers when you create it.

How Alpha Messages Occupy Memory

When you store an alpha message, it is stored in data registers, just as numeric values are. To avoid a conflict with previously stored alpha or numeric data, you need to understand how alpha messages occupy memory.

A stored alpha message occupies 10 data registers. This is because the entire contents of the 80-character alpha register are stored. If the message is fewer than 80 characters in length, the remaining portion of the alpha register contains blanks.

For example, if you store the message "RESULT = " in data register 000, it occupies registers 000 through 009.

Register

Contents

000RESULT =
001
...( registers 002 through 007 )
008
009

Although data registers 001 through 009 are filled with blanks, they are part of the alpha message and should not be used to store any other data.

Before designating a location to store a message, make sure you have 10 consecutive data registers available that do not contain important information.

Storing an Alpha Mesasge

The { STA } (store alpha) selection letes you store the currently displayed alpha message in a specified series of data registers. This function is primarily useful when you plan to redisplay an alpha message after displaying another alpha message.

To store an alpha message is data registers:
  • Activate the alpha mode and create the message.
  • Press { STA } and enter the address of the first of the 10 data registers you want to hold the message.

Recalling an Alpha Message

The { RCA } (recall alpha) selection lets you redisplay either the most recently displayed message or a message you have stored using { STA }.

To redisplay an alpha message:
  • Activate the alpha mode.
  • Use the key sequence that applies to you:

    { RCA } [ = ] - to redisplay the most recently displayed message after it has been erased by a numeric value. The message appears with the cursor positioned where it was before the number was displayed.

    { RCA } nnn - to redisplay a message you have stored using { STA }, press { RCA } and enter the data register where you stored the message. The message appears with the cursor positioned immediately following the last nonblank character.

Note:

If you use { RCA } to recall the contents of data registers that do not contain a stored alpha message, the calculator displays the alpha characters that correspond to the numeric values stored in the registers.
