j. As soon as you press the Exit key, the billboard will announce that the page
on display is “volatile”—that is, it is not yet stored in EEPROM memory.
THEREFORE, IF THE MAINFRAME IS NOW TURNED OFF, THE NEWLY COM-
POSED PAGE WILL BE IRRETRIEVABLY LOST.
If you want to take another look at the Page Directory at this point, to see what
pages are as yet unused, simply type
DIR [CR], as in Step c, above.
k. After examining the directory, you will have to “recall” to display the still
volatile page you have just composed, by entering from the keyboard a com-
mand of
RCL [CR]
l. To permanently save this page, make sure the EEPROM Write Protect function
is enabled (see Step a, above), and then type
SAV n [CR]
where “n” is a page number not presently being used.* The billboard will tell
you when the page is safely in EEPROM storage. Press CARRIAGE RETURN
once more to remove the billboard message.
m. To verify the saving of the new video page, call back the Page Directory by
typing
DIR [CR]. It should show the page just placed in EEPROM storage (as
“Page No. n”), with its relative memory size.
n. Now call Page No. n to display once more by pressing the
Page key and typ-
ing the number “n,” followed by
Retrn. While Page No. n is still on the screen,
press the
Page key (only), followed by Retrn. The appropriate response
(
PAG = n) should appear in the billboard.
o. Press
Retrn once more and note the “logo” text presently in the display bill-
board. Change the “logo” to “
ABC CORP.” by typing
LGO = ABC CORP. [CR]
p. Now enter an LGO command to change the “logo” back to its original text, or
to whatever other text you want. For a CRT display, the “logo” can take up to
27 alphanumeric characters, including spaces.
q. To designate a new “sign-on” page to be displayed automatically on system
powerup, you can enter a command of
SOP = p [CR]
where “p” is the number of any video page currently in EEPROM storage.
Having gone through the above page composition and storage procedure—and,
ideally, having gone back and tried to compose a few video page formats of your
own design—you may want to consult Section 2.C of the
System 10 Guidebook
for instructions on additional video setup procedures, including
• CRT adjustment, including VIDEO MODE and refresh rate
• DELETION of display fields and video pages
• line duplication and repeated character entry
• establishment of “ASSOCIATED” FIXED TEXT

* Note that “n” could also designate an existing page in storage which you wish to replace with
the page now on display. In this case, the system will automatically display the currently stored
“Page No. n,” with the billboard question
PAGE ALREADY EXISTS AS SHOWN, DELETE?
See Section 2.C.7 of the System 10 Guidebook for further instructions.
