PREFACE
RANVUE is a vue like data editor used for vueing Random files
on the Alpha Micro AM100/L. It allows the editing of any
Random file no matter the size or structure of it's data. It
can save time in writing a new program for a specific
Random file each time you need to get in, locate, and correct
or modify data. This program enables you to manipulate data
on all Random files. With a good knowledge of this Manual and
a little practice you will be able to quickly locate
and manipulate any data in the Random file.
RANVUE'S DISPLAY WINDOW
Only 512 bytes of the Random file may be displayed on the
terminal screen at any one time. You should consider this
display to be your window on the file through which you vue
the data in that portion of the file. Unlike VUE, moving the
cursor past the edge of the screen only brings you back to the
beginning or end of the 512 byte record. Escape (ESC) and then
a character allows you place the window anywhere in the file.

CHAPTER 1
SCREEN MODE
When the cursor is within RANVUE's window on the file you are
said to be in Screen Mode. As well as Modifying and Deleting
data in this mode by typing over the data displayed, there
are numerous characters which allow you to rapidly move the
cursor around throughout the file. RANVUE is always in the
screen mode unless an ESC is pressed. This puts you in the
command mode which allows many file manipulation modes by
pressing the corresponding character. For the ease of
explaination when talking about these command mode
characteristics we will explain them as ESC then the character
As at any point in Screen mode you may press ESC C to end
RANVUE, with all file modifications made, and return to AMOS.
While in the screen mode control characters are used.
CURSOR MOVEMENT
Cursor Right: ^ L
To move the cursor right one position within the current
line, press ESC L (or use the right arrow key on many
terminals). If the cursor is at the end of the line, it will
"wrap" to the beginning of the next line below. If the
cursor "wraps" at the end of the current page, the cursor will
wrap to the begining of the 512 bytes already displayed.
1
Cursor Left: ^ H
To move the cursor left one position within the current
line, press ESC H (or use the left arrow key on many
terminals). If the cursor is at the beginning of the
line, it will "wrap" to the end of the previous line above.
If the cursor "wraps" at the beginning of the current
page, the cursor will wrap to the end of the current page.
Cursor Up: ^ K
To move the cursor up one line in the file, press ^ K (or
use the up arrow key on many terminals). The cursor will be
at the same position within the new line as the previous line.
If the cursor is within the first line of the current
page and you move up, the cursor will move to the last line
of the current page.
Cursor Down: ^ J
To move the cursor down one line in the file, press ^ J (or
use the down arrow key on many terminals). The cursor will be
at the same position within the new line as the previous
line. If the cursor is within the last line of the current
page and you move down, the cursor will move to the first
line of the current page. Pressing RETURN, will place the
cursor at the beginning of the next line in the file
regardless of its position in the previous line. Note that
when the cursor is within the last line of the entire file no
other movement occurs.

1.2 LINE MOVEMENT
Cursor to beginning of Line: ^ U
To move the cursor to the beginning of the current
line, press ^ U.
Cursor to End of Line: ^ N
To move the cursor to the end of the current line, press ^N.

CHAPTER 2
COMMAND MODE
Some commands in RANVUE are not available in Screen mode
but are executed in what is know as Command mode. To toggle
Command mode when you are in Screen mode, press ESC (or
whatever key on your terminal sends the ASCII Control
signal ESC). An arrow ">" will appear with the cursor to the
right. The ">" is the RANVUE prompt which means that
RANVUE is waiting for your command. If RANVUE does
not understand your command, it prints "What?" and dings
your terminal once. You simply re-enter the command
properly. Whenever you wish to go back to Screen mode,
press RETURN.

PAGE MOVEMENT
Beginning of File: ESC H
To move the cursor to the beginning or first record of the
file press ESC H.
End of File: ESC E
To move the cursor to the end of the entire file, press
ESC E.
Page Up: ESC R
To move the cursor back one page in the file, press ESC R.
The cursor will be at position one or the first byte of the
page displayed Note that when the cursor is within the first
page of the file no upward paging occurs.
Page Down: ESC T
To move the cursor down one page in the file, press ESC T.
The cursor will be at position one within the new page
displayed. Note that when the cursor is within the last page
of the file no downward paging occurs.
Specify Page: ESC P
To move the cursor to a specific page in the file, press
ESC S followed by a page number. If the number entered is
greater than the possible number of pages in the file the last
page will be displayed and a bell will ring. If a number less
than 1 is entered page 1 will be displayed and a bell will
ring.
5
DATA EDITING
String data: Type-over
String data may be modified by simply typing new characters
over old characters on the screen. For instance,
suppose that you have an invalid date in the file and
displayed on the screen as "102482". You wish to change that
date to be "012482". First position the cursor on the "1" and
then type "01" right over the "10". The date both in the
file and on the screen is now "012482".
Floating Point data: ESC N then F
Each floating point number in a random file always takes up
six bytes. To this end RANVUE has the ability to display any
six byte group as a decimal value at any point in the random
file. Therefore press ESC N then F for floating point
numbers. Then enter the byte location of the floating point
number. The number will be displayed . Type any new number,
positive or negative, that you wish stored at that location
then press RETURN. RANVUE then returns to the screen mode.
Binary data: ESC N then B
Each binary number in a random file takes up from 1 to 5
bytes. At this time RANVUE has the ability to display only
any 1 to 2 byte group as a decimal value at any point in the
random file. Therefore, press ESC N then B for binary
numbers. Then enter then byte location of the binary number.
Then enter the length of the binary number 1 or 2. The number
stored at that location is displayed. Type any new
number, positive or negative, that you wish stored at that
location then press RETURN. RANVUE will then return to the
screen mode.
6
DELETIONS
Character at a time: Type-over
To delete data character at a time, you may use the Space Bar.
RUB or DEL key do not work in the screen mode. You may use
any character you wish (e.g. in AlphaACCOUNTING a "]" is used
to fill the logical record after which it is simply sorted to
the end of the file).
Pages at a time: ESC C
To delete groups of data at a time, enter an ESC C. RANVUE
now requests the page numbers of data to be deleted. If, at
this point, you do not wish to delete the data type a CR. The
data from the current page to the end page number that you
entered will be writen over.
RANVUE next requests the fill character to be used. Simply
press the key of the character to be used. If you press
RETURN, the default character,"]" will be used.
SEARCH: ESC S
To locate a particular word or string of characters in the
file, type ESC S. RANVUE then requests the string you are
searching for, then press RETURN. Note that RANVUE always
begins its search starting at page 1 and continues to the end
of the file. If RANVUE finds your string it displays the
page where the string was found, with the cursor on the string
in lower intensity. You are now back in Screen mode and may
resume editing. To find the next occurence of the string,
press an X. When RANVUE can find no more occurences of
the string, it returns you to Command mode. NOTE: If RANVUE
is within SEARCH and has not yet found a match, a CR will
immediately end the SEARCH and return you to Screen mode with
the cursor at byte 1 on the current page in the file that
SEARCH had reached when aborted.
7
REPLACE: ESC R
To replace a particular word or string of characters in the
file, type ESC R. RANVUE then requests the string you wish
to replace, then press RETURN. RANVUE now prompts you, with
"With ?", for the characters you wish to replace the first
string with. If RANVUE cannot find the string to be
replaced, it returns you to screen mode record #1.
Otherwise, it displays the page where the string was found,
with the cursor on the string in lower intensity. RANVUE now
waits for you to press one of the following keys:
Y - yes, replace this string and go to the next match
N - no, go to the next match without replacing this string
carriage return - return to screen mode without replacing
this string.
NOTE: If RANVUE is within REPLACE and has not yet found a
match, a CR will immediately end the REPLACE and return you
to Screen mode with the cursor at byte 1 on the screen that
REPLACE had reached when aborted.
GLOBAL ESC G
To replace ALL
particular words or strings of characters in
the file, type ESC G. RANVUE then requests the string you
wish to globally replace, then press RETURN. RANVUE now
prompts you, with "With ?", for the characters you wish to
replace the first string with. If RANVUE cannot find
the string to be replaced, it returns you to screen mode
record #1. Otherwise, it displays the page numbers it is
searching, and replaces every occurance of the string it
finds. RANVUE does not wait for your Y or N answer as it
globally replaces every occurance of the string it finds.
8
BACKUP: ESC B
RANVUE always has an immediate backup of the page being
displayed. If you modify the page being displayed and then
decide you do not want the changes made, then type ESC B.
RANVUE then will display the backup and ask if you wish to use
it. A "Y" will REPLACE the screen with the current backup. A
"N" will use not use the backup. This immediate mode only
stores the last current modification of the screen as first
displayed. If you make a change, display another page, and
then redisplay the 1st page and ask for a backup, the backup
will be what was written in previously.
IF you invoke RANVUE with the option "/B" RANVUE will create a
backup copy of the random file when it is invoked. The backup
file will be "on-line" throughout your editing of the
original. Therefore if you make a mistake while editing you
simply press ESC B to immediately restore the Current Page
from the backup file. If you have already left RANVUE,
simply use the COPY.PRG to restore the entire original file.
The backup file has the same filename as the RANVUE'ed file
with the extension of ".DAK". NOTE: If you do not have
enough free space on the disc for a backup and you set do not
use the "/B" option then, you should manually make a copy of
the random file on another disc before editing.
PRINTING: ESC O
RANVUE allows you to print the random file. Only printable
ascii characters will be printed. Type ESC O. RANVUE then
requests how many bytes a line you wish to use. Enter it then
RETURN. Next it requests which page to start printing and then
which page to end printing. Enter this information then
RETURN. Finally RANVUE asks how many lines per page to print.
Upon entering this data and RETURNing, RANVUE will clear the
screen, count the pages, and spool the file RANVUE.LST to your
default printer, and return to the screen mode, on page 1.

SUPPORT
RANVUE can support many terminals. All the options at this
time must be program dependent though. The characters that
allow GRAPHIC CAPABILITIES must be change to correspond with
your terminal. The LOW and HIGH intensity display capabilities
must correspond with those applicable for your terminal. These
"customized " features must be made in the listing RANVUE.BAS
under the :
MAP STATEMENTS:
GRAPHON - graphics on character or characters
GRAPHOFF - graphics off character or characters
LOW - display low intensity character or characters
HIGH - display normal intensity character or characters
File Extensions
On the Alpha Micro, files are specified by a file name of
one to six characters followed by a period "." follow by an
extension of zero to three characters (i.e. "FILNAM.EXT").
