Command DRLIST
-------------

Purpose: To display the contents of an ASCII text file, line by line
with the aid of scrolling, positioning and filtering commands.

Format: DRLIST [d:][path]filename[.ext]

Remarks: An ASCII file of any size may be listed.

The "filename" is optional. If omitted, you are prompted to
to enter a filename. You may include drive, path, and wild
cards in the file name. The first file which matches the name
is displayed until an end-of-file character is encountered. Each
file which matches the "filename" may be displayed.

DRLIST was designed to display ASCII files. That is, files
which contain text and not binary or control codes. Text
characters usually range from a value of 32 to 127. To view
binary files (COM, EXE, etc), the D-key hex dump display option
is available.

Characters below 32 (a blank) are replaced with a funny
character to indicate that a non-displayable character has been
encountered. This character is an upside-down question mark.

Characters above 127 may be valid graphic characters, and may
be displayed if the '8' command is in effect. To insure that
characters above ASCII value 127 are not displayed, use the '7'
command.

The top line of the display gives the file name, current right
scroll offset, and the file's creation date and time. Optionally,
a ruler may be displayed on the top line by using the R key.

The file is displayed with one logical record on each
80-column display line. A logical record ends in a linefeed.
The maximum logical record may be 256 characters long. If the

record exceeds 80 characters, you may view the portion beyond
the 80 columns by using the scroll right command, or by using
the Wrap feature.

The Wrap command toggles ON or OFF the wrapping of lines
longer than 80 characters. With Wrap on, lines are displayed in
their entirety, 80 characters per display line. The scroll
-left and -right functions are disabled when Wrap is ON.

The file may be PRINTed as it it displayed. The P command
toggles the printer on or off. When first entered, the P
command causes the current screen to be printed. As new lines
are displayed, they too are printed. Printing may be stopped by
entering another P command. The PrtSc key may also be used, but
the title and prompt lines will be printed with the lines of the
file. Empty lines cause a line to be skipped on the printer. The
letter P is displayed in column 80 of the top line while printing.
DRLIST Page 2

Display format
--------------

The monitor display is defined in terms of lines and columns.
A typical monitor can display 25 lines of 80 columns each. DRLIST
attempts to use the number of lines and columns for the monitor
mode in use. For example, if the monitor is in 40 column mode,
DRLIST displays only 40 characters per line.

The top line of the display is called the Status line. The
bottom line is called the Command line. The remaining lines are
called the primary display window, and are usually lines 2
through 23.


Status line format
------------------

The Status line has the following format:

DRLIST lllll +sss mm/dd/yy hh:mm bKMPSW - filename

where,

'DRLIST' is the name of this program

'lllllll' is the line number of the first line in the

display window (usually on line 2)

'+sss' if displayed, this is the Scroll amount, in
multiples of 20, corresponding to the number
of columns that the display has been shifted
to the right to view records longer than 80

'mm/dd/yy' is the file's creation date
'hh:mm' is the file's creation time

'D' indicates that the hex Dump display option is in use
'b' indicates whether the 7-bit, 8-bit, or *-option is
in use
'K' indicates that the Keyboard flush option is in use
'M' indicates that tests for monitor retrace are not made
'P' indicates that Print is in use
'S' indicates that the C (file sharing) is in use
'W' indicates that the Wrap mode is in effect
DRLIST Page 3

Command line format
-------------------

The Command line has the following format:

command message ______ Keys: Num-keypad Q=next X=exit ?=Help

where,

'command' indicates the current process:

'Command' you are being asked to enter a command
enter the letter, or press the keys for
the action to perform

'Reading ' the file data is being read
'Filter ' the file data is being formatted for display
'Scanning' the Scan/Find text is being searched for

'Scan ' you are being asked to enter text to locate
'Find ' in the file, up to 31 characters may be entered

'# lines?' you are being asked to enter a 1 to 5 digit
number that is the amount of lines to skip

'Line #? ' you are being asked to enter a 1 to 5 digit
line number to which the display is to be
positioned


'message' may be one of:

'*** Text not found ***'
the Scan/Text was not found in the file

' *** Top of file ***'
the first line of the file is being displayed

' *** End-of-file ***'
the last line of the file is being displayed
DRLIST Page 4

Key functions and Commands (cont.)
--------------------------


________________________________

Numeric keypad with NumLock on
________________________________


# over key Function
------------- -------------------------------------------
1 END position to end of file (bottom)
7 HOME restart from first line (top)
9 PgUp scroll up one page, 23 lines
3 PgDn scroll down one page, 23 lines

4 left arrow scroll left 20 columns
6 right arrow scroll right 20 columns
8 up arrow up one (previous) line
2 down arrow down one (next) line


Control key Function
----------- -------------------------------------------

alt-C clone DRLIST.COM, change colors or options
permanently in program file


Positioning to Lines
--------------------

Each displayable line of the file is assigned a line number.
The first line is assigned line number 1. The highest allowable
line number is 65535. In order to determine the last line
number, the entire file must be read. For this reason, the
first time that the END (bottom) command is issued, it will take
longer to process.

If the Wrap option is in effect, there is one line number
required for each 80 bytes of the file records.

If the hex dump option is in effect, there is one line number
required for each 16 bytes of the file.

You may position to a specific line number by using the
# character key. When # is entered, you are prompted for the
line number to position to. Enter the 1 to 5 digit line
number. The display will now begin with that line number at the
top of the screen.

To position forward or backward, you may use the + (plus), or
- (minus) keys. You are prompted to enter the number of lines
to be skipped. The display resumes at the line number shown on
the top (status) line, plus or minus the number of lines that
you specified.
DRLIST Page 6

Cloning procedure
-----------------

The screen colors, the display retrace testing (M), the file
closing (C) and ruler (R) options may be permanently set in
the program by using the alt-C cloning function.

For cloning to take effect, the program must be called
DRLIST.COM and it must be on the current drive and in the current
directory.

The clonable options (command toggles) are:

M = Mono monitor, affects retrace testing, no effect with ANSI
R = use ruler on top line,
C = file(s) are shared, not left open while displaying
D = hex dump display, like the DEBUG format
W = Wrap long lines
E/S/* = display all 256 values, or 7-bit, or special cases
K = flush Keyboard each time a command is read


DRLIST Page 7

DEBUG Information
-----------------

An alternative to cloning is to use DEBUG to make permanent
changes. Here is a list of key items and their addresses:

0126 - special lines 1 and 25 colors, default is 01 (blue)
Refer to a technical reference guide for the
attribute values for the colors that you want.
0128 - normal lines 2 thru 24 colors, default is 02 (green)
012A - bright color for Find/Scan, default is 0C (bright red)
012C - options; bits 0 through 6
MRSD WHK. M = mono, x'01'
R = ruler, x'02'
S = shared, x'04'
D = hex display, x'08'
W = wrap mode, x'10'
H = hi-bit on, x'20'
K = kybd flush, x'40'

By specifying the bit value, the option is enabled.
For example, to enable Shared and Retrace, specify
a hex value of 05.

The letters and command keys may also be changed. There are
two tables involved: WHAT and WHERE. The WHAT table contains a
list of one-byte keyboard codes. The WHERE table contains a
list of two-byte addresses. If you really want to change the
codes, here are the DEBUG addresses:

0472 - *WHAT* eye catcher
0478 - list of ONE byte command letters and characters

04A5 - *WHERE1* eye catcher
04AD - list of corresponding two byte offsets to routines


NOTE: These DEBUG addresses are version dependent.
==================================================
DRLIST Page 8

Screen attributes
-----------------

The colors used for displaying the titles and main body of
text may be changed temporarily or permanently. To make a
permanent change, the cloning command alt-C is used. It
requires that the DRLIST.COM program file be on the current drive
and in the current directory.

There are three classes of attributes used. One for normal
display lines - lines 2 to 23 - another for special lines -
lines 1 and 24, and a third for the Find/Scan color. The border
is not changed. The foreground color applies to the characters
displayed.

These color attributes may be changed by using function keys:

For the main body of text:

, (comma) - background color
. (period) - foreground color

For the top and bottom lines:

< (less than) - background color
> (greater than) - foreground color

Only one line is redisplayed when you change the "normal"
colors, background or foreground. The display is scrolled
up one line to reveal the next line with the new colors.

Once you have decided upon the colors, use the alt-C key
combination to change the DRLIST.COM program file.

If DRLIST is used from a remote computer, the default colors
used by DOS will be changed to those used by DRLIST.

DRLIST Page 9

Scanning for text
-----------------


You may use Find (\) to search for text regardless of the
case, or you may use Scan (/) to find an exact match.

To scan for a character string, type a slash (/) followed by
one or more (up to 31) characters. The scan text, but not the
slash, is displayed on the command line. The scan is case
sensitive. That is, lower case scan text will only match lower
lower case file text.

While the program is searching for the text, the bottom
display line is changed to say "Scanning".

If the text is found, the line containing it is displayed as
a high-intensity line (bright color).

If the text is NOT found, the bottom line (24) is changed to
say '*** text not found ***', and the display remains unchanged.

To find the next occurrance of the same text, use the A)gain
command, or press the A key.

If the PCED keyboard enhancement program is installed, the
up/down cursor keys may be used to recall and edit previously
entered Scan/Find text.

In a shared file environment, if the file changes while being
listed, the file position may become invalid. Use the 7 letter
command to insure proper file synchronization, or use the C
(shared) option.
DRLIST Page 10

Filtering
---------

Filtering is the term used to describe the process that DRLIST
uses to format file data for displaying on a monitor. After data
is read from a file, it is filtered. The method of filtering
depends upon the options in effect.

For a typical ASCII text file, the filter removes carriage
return and line feed characters, and expands TAB characters.

The S, E, and * (asterisk) commands determine whether
characters above ASCII-127 are displayed. If the hi-bit option
is off (S command), the filter strips the high order bit from
each character. If the hi-bit option is on (E command), all
characters, including graphic characters above ASCII-127, are
displayed.

The * (asterisk) command displays only ASCII characters
below 128 (x'80'), but treats the special characters x'8A' and
x'8D' as line-feed and carriage-return control characters. Any
other characters above 127 are ignored.

The Wrap option causes the filtering to insure that no line
exceeds the width of the monitor, e.g. 80 characters.

The hex dump option (D key) causes the filtering to reformat
the file data into a DEBUG-like display format. The largest
file that can be "dumped" is 1 million bytes.

NOTE: The EOF control character is ignored in this version.

DRLIST Page 12

Special ANSI version
--------------------

The special ANSI version of DRLIST uses DOS function 21 hex for
all display I/O. This means that the display will be slower,
but it also means that ANSI escape squences can be displayed,
and that DRLIST can be used by a remote computer via the CTTY
or BBS DOORS facility.

The use of function keys, e.g. F1, and the cursor positioning
keys are not supported by all DOS environments or communications
programs. Therefore, the cursor positioning keys have been
redefined to be the numbers over those keys. By setting NumLock
on, the cursor positioning keys will have effect. For example,
the PgUp key may not work, but the 9 key will perform the PgUp
function. The Fn (function) keys have had letters assigned to them.
