MORE.EXE v1.3 -- File Pager

First andforemost, MORE now requiresDOS v3.0 or later to run. No
exceptions. Ifyou have a version of DOS earlier than 3.0, you can either
upgrade (recommended), or you can use MORE v1.1 (which is still available.)

The MORE archive includes the following files:
MORE.DOCthis documentation file
MORE.EXEMORE itself
RUN.COM used for executing batch files from MORE
MORE.CThe source code for MORE

STRINGS.COMAnalyzes binary files for text strings
STRINGS.DOCDocument for STRINGS.COM

MORE itself creates theconfiguration file (MORE.CFG) in the directory
containing MORE.EXE. Therefore, this file is not included inthe archive. If
the file is not found, the information is read from a table of internal
defaults.

MORE is a program which (essentially) allows you to scroll through a file
and examine its contents.

There are two ways to use MORE:
MORE
or, like the DOS more:
TYPE | MORE

Either way, your file will be read in. If MORE is unable to read your file
(such as if you left your drive open or the file doesn't exist), it will inform
you: "more: unable to open file". If you supply more than two arguments, it
will inform you as to the syntax.

However, if you forget to include a filename of some sort, it will just sit
there with the cursor flashing, waiting for input. The easiest way out of this
mess is to press ^Z and Enter. Then press ESCto exit. Next time remember to
include a filename. (This is due to the fact that if you don't redirect, the
standard input -- which MORE reads if no filename is supplied -- is the
keyboard.)

After MORE has read your file, you can scroll through it using the arrow
keys. The Up and Down arrow keys scroll one line up or down; the PgUp and PgDn
keys scroll a page. The Rightand Left arrowkeys scroll 20columns left or
right. The Home and End keys go to the beginning and end of the file. Ctrl-PgUp
and Ctrl-PgDn scroll half pages. To exit (after you have read the file), press
Escape. Your currentposition within the file is shown in the upper-right
corner of the screen, in the form of Line, Column. Pressing F1 will show a list
of possible operations.

MORE also featuressearching functions. There are two types of searches,
normal and case sensitive. The normal search thinks that A and a are identical
for example, but to the case sensitive searchthey wouldn't be. The searches
will only search beyond the current line (theline at the top of the screen)
and will not find a word ON the current line.

To use the searches, push 'F' (for a standard search) or 'C' (for a case
sensitive search.). Then type the word or phrase you would like to search for.
You can search for up to 65 characters at a time.

If the find routine is unable to locate the phrase, the computer will beep
and the screen will remain where it was. If it was able to locate it, then the

screen will move so the line containing the phrase is at the top of the screen.

If you would like to repeat a search, use 'N' or 'B' -- find Next or find
Backward. The find next command worksas if you retyped Find and the phrase
you're looking for. However, the backward command looks BEFORE the current line
for the phrase. This is useful if you accidently went to far, for example.

If you want to cancel the search, press Escape. ONCE! If you press it more
than once, MORE will exit to the DOS prompt. It may take a while for the search
to end.

You can also search for lines. To do this, press 'L', and then type the
number of the line youwant to find. (If the line doesn't exist, or what you
type isn't a number, the program beeps at you.)

You can also store locations in the file for looking at later -- afeature
called bookmarks. To use this, type 'S', and then type a number and enter to
set the bookmark. Any number 0-9 is usable. (If what you type is not anumber,
the computer will beep at you). Then, when you want to go back to it, type 'G'
and the number again. (If what you type is not a number, again, the computer
will beep. It will also beep if you haven't defined that bookmark yet.)

Blocks are used in MORE to select text to be written to the disk or
printed. When you define blocks, the line at the top of the window (the current
line, under the top information line) is selected. The text you markfor the
block is highlighted.

To define a block, use the '+' key to set the top of the block and the '-'
key to set the bottom of the block. (Either set will work.) But make sure that
the line you want to mark is at the very top of the screen!

To clear the block, press '*' (again, either one will do). Note that this
does not erase the block, but only unmarks it.

To print the entire file, press 'A'.

If you decide to cancel printing after it started, press Escape. It may
take awhile, but do NOT repeat thekeystroke unless you want to exit. The
keystroke will register as soon as theprogram has an has a chance tolook at
the keyboard.

You can write either a block, or the whole file, to another file. To do
this, type 'D' to write the current block (if no block is defined, MORE beeps).
Then type the name of the file you want towrite to. If the file already
exists, you are giventhree choices.Push 'Y' if you want to overwrite the
file, push 'N' (or Esc) to cancel, or push 'A' to append the text to the file.
Writing the whole file uses the same process, but type 'W' instead of 'D'. You
can use Esc to cancel the write. The file will be deleted UNLESS you specified
to append to an existing file (if you did, then you have to clean up the mess.)

If the file was collected from the standard input, you wrote it out, and
you did not append it on to another file, MORE will change the top line to show
the name of the file you wrote it out to, and will let you use the 'E' command.

To call up an editor from MORE, first set it up (exact procedure described
below). Then you push "E". If the file was collected from the standard input
and not written to disk using the "W" command, this will be ignored. MORE does
not return after your editor has ended.

MORE does have some limits. You can't load files larger than available
memory and lines are limited to 2048 characters in length.MORE can't read
binary files (such as program files) except with thehelp of a program like
STRINGS (which is included). No problems will occur, but the results will be
somewhat wierd.

If you go beyond the limits set forth in the program, the program will
politely inform you with a message like "more: insufficient memory". Lines
longer than 2048 characters will be split into multiple lines. However, after
such a split, tab characters become small circles and don't space properly. In
fact, this can happen to any long line.

Normally, MORE displays the name of the file you're viewing on the top
line, but if it is too long, it displays a copyright message instead. It will
also display the copyright message if the input was collected from the standard
input as no filename is available.

To set up MORE, you use the keys F7 through F10. F7 changes the screen
colors. To use this, simply use the Up/Down arrows to move the pointer (->) to
the color that you would like to change, and then use the Left/Right arrows to
increment or decrement the number. Both wrap. The line at the top of the screen
shows the numbers for background and foreground colors, and the three lines at
the bottom of the screen show the colors currently selected. To exit the
color-changing mode, hit Esc, which also redraws the screen in the colors you
selected.

Tochangethe printer port, push F8.Then you can either enter a new
printer port (the logical DOS file used for output to the printer) or press Esc
to cancel the operation. Possible printer ports are listed on the bottom of the
screen, and include 'PRN' (the default), 'LPTx' (parallel port #x), and 'COMx'
(serial port #x), as well as standard DOS files.

Changing the command used to activate the editor is done by firstpushing
F9. Then you can type command that you want to use (replacing the filename to
edit with an @sign), or hit Esc to cancel the operation. Normally, what you
type would be exactly the same as what you would enter on the command line, but
if youneed to use abatch file to run your editor, you must preface the
command with "RUN", and you must have the program RUN.COM (which comes with
MORE) somewhere in the path. This is done to minimize the memory overhead.

Pressing F10 writes the configuration file to disk (it's MORE.CFG in the
directory that contains MORE*.)

Version 2 will be available as soon as I get around to it. Version 2 should
feature the ability to spool files to disk (allowing viewing of any length
files), and any improvements suggested by my users. More interim releases will
be released before version 2, though.

Changes in version 1.2 include the ability to call up an editor from MORE,
the ability to write input collected from standard input to disk, and changing
the screen colors and printer port.

Changes in version 1.3 include improved memory management (allowing loading
of larger and wider files), reorginazed (prettier) help, 2048-character lines,
no maximum file length (aside from memory**), about50K ofextra room for
loading files, and a command for going to the very left margin of the file. It
also adds commands for storing and going to bookmarks within files and locating
lines. The command for writing files out to disk was revised, and a command
was added for writing a block out to disk.

For those who are interested, RUN.COM simply calls COMMAND.COM toexecute
the command specified as its argument.

*For those who care, MORE actually reads the actual name of the program off
the command line and uses that. So, if you rename MORE.EXE to LOOK.EXE, for
example, the configuration file would be named LOOK.CFG.

**Actually, there is an absolute limit at 32000 lines. But there is not
enough memory available for loading more than about 26000 lines (even totally
blank), so this is not important. It will be, however, in Version 2.
