FILEBROWSER OPTIONS
FileBrowser may be loaded with the command line:
FB [-options] [speed] [editor] [d:][\path\]FILENAME[.ext]
The "options" currently available are 'q','m','s','e','w' and 't':
q : (Quiet Load) - Omit display of title screen before loading file.
m : Use black-and-white windows instead of colour.
s : specify CPU speed using the variable 'speed' (= integer in the
range 1-50). If 's' is not specified, speed defaults to 5.
e : specify editor calling name using the variable 'editor'
w : load a Wordstar (tm) document file: if omitted, the file is assumed
to be an ASCII file. (The extended ASCII character set is supported).
t : Do not expand tabs. The 'Tab' character will appear as a distinctive
graphic (ASCII 09). If omitted, tabs are expanded to spaces.

GETTING HELP ON FileBrowser COMMANDS
FileBrowser commands are entered from the Menu Bar (activated by pressing
the "Ins" key). To execute a command from the Menu Bar, move the Highlight
to the desired command and press "Return", or just type the first letter
of the command. To get help on the Highlighted command, press the "F1" key.
01
PRINT
The PRINT command is used to copy part of the current file to a new
file or to the lineprinter (device PRN). If the "Print to File" option
is selected, you will be prompted for the new filename (which can include
optional drive and path, e.g. d:\path\file.ext). If the file specified
already exists, you have the option of overwriting it or appending text
to it. If you enter an illegal file name, an error message will pop up.
After specifying a file or printer, you will observe that the top line
of text in the main window is highlighted in reverse video, and a blinking
cursor appears on the next line. You may move the cursor down to subsequent
lines - as this is done, the line above the cursor is marked. To 'unmark' a
line, use the Up Arrow key. When you have marked the desired number of
of lines, press the "Return" (or "Enter") key, and the marked lines will be
copied to the file or printer (in ASCII format). Press the "Esc" key to abort
the 'FILE' operation and return to 'Browse' mode.

The "Print to File" command may be given while in 'Browse' mode by
pressing the "F" key; the "Print to Lineprinter" command may be given
while in 'Browse' mode by pressing the "P" key.
02
BROWSE
The BROWSE command is used to view the current file - it just causes
FileBrowser to enter 'Browse' mode, (which is the default mode). There are
several options:
- To scroll through the file, use the Up and Down arrow keys to move up
or down a line; use the 'PgUp' and 'PgDn' keys to move up or down by
one page. The 'Home' and 'End' keys move to the beginning or end of
the file, respectively.
- To move forward or back by lines (where is an integer):
first press the "+" key, then enter the value of (you will get a
prompt to do this on the bottom line of the screen), then press the Down
arrow, or Up arrow as desired.
- To automatically scroll forward or backward, press the "*" key (aster-
isk) followed by the Down arrow or Up arrow key. To select the speed,
type an integer from 0 to 9. [9 = fast, 0 = slow, 5 = medium].
Press any key to stop scrolling.
- To move forward or backward to the next or preceding MARKed lines, use
the Right or Left arrow keys, respectively.
If the screen gets mangled for any reason, press Ctrl-L (^L) to redraw it.
03
SEARCH

FileBrowser incorporates a simple pattern matching function, which
may be used to locate a string of text in a file. A 'pattern' can contain
words, (a 'word' is defined as a string of alphanumeric characters), and
the wildcard symbol "*". The symbol "*" matches any number of words,
(including no words!). Thus, the pattern "the * fox" will match all of the
strings: "the fox", "the brown fox", "the quick brown fox". The symbol "*"
is only legal inside a pattern string.
When 'SEARCH' is invoked, you will be prompted to input a pattern.
FileBrowser will automatically process your input into a legal pattern (you
will have a chance to correct errors). The search then proceeds forward
from the Top Line displayed in the main window, and is on a line-by-line
basis (patterns extending over two lines are not found). At each successful
'hit', the line which matches the pattern will be highlighted, and you will
be asked if you wish to continue. If you have selected the "SEARCH AND
MARK" option, the matching lines will be permanently marked (see MARK)
Note: The SEARCH command may also be given in BROWSE mode by simply
pressing the "S" key, or the "Ctrl-S" (^S) keychord for SEARCH and MARK.
04
MARK
There are two commands possible in this mode: MARK and UNMARK. The
(M)ARK command allows you to put a permanent 'mark' on a line, and highlight
any portion of it. The (U)NMARK command is used to clear all 'marks' from
the text in the buffer.
When the MARK command is given, a cursor appears in the upper left-
hand corner of the main window; use the arrow keys to move the cursor to
the start of the text you wish to highlight (you can only move to text which
is visible - scrolling is disabled), and press the "Return" key. Then use
the Right arrow key to add letters to the highlighted area (the Left arrow
key may be used to back up) and press "Return" when you are finished. If a
line is already marked, you can unmark it by placing the cursor at the be-
ginning of the line and pressing "Return" or "Esc". At any time in the MARK
operation you may abort and return to BROWSE mode by pressing the "Esc" key.
The SEARCH and MARK mode allows you to semi-automatically mark all instances
of a SEARCH pattern within a file. It is entered from the SEARCH menu.
The MARK and UNMARK commands may be given in BROWSE mode by pressing
the M and U keys, respectively; SEARCH AND MARK command is given by pressing
the "Ctrl-S" (^S) keychord.
05
DOS

The 'DOS' command suspends FileBrowser and returns to the DOS operating
system: a second copy of the DOS command shell is loaded. To alert you
that you have loaded another shell, the cursor will change to a small
flashing box instead of the normal flashing underscore.

You may now carry out disk maintenance operations, run another program,
etc. The FileBrowser environment remains resident in memory; to return to
FileBrowser, type the command 'EXIT' at the DOS prompt.

The "DOS" command may be given while in 'Browse' mode by simply
pressing the 'D' key.
06
EDIT

The "EDIT" command allows you to edit the current file using the
text editor of your choice. You may specify the editor in the command
line when starting FileBrowser, or by setting the DOS environment
variable "EDITOR". If the variable "EDITOR" is not set, FileBrowser will
attempt to load the "vi" text editor. Whatever text editor you choose,
it must be one that can accept the file name in the command line, e.g.
"vi filename".

Be sure that the editor you will use is in a directory specified by your
DOS path (environment variable "PATH").

The "EDIT" command may be entered from the menu line, or by pressing
the "E" key while in 'Browse' mode. When the "EDIT" command is given,
FileBrowser writes a short Batch file in the same directory as the file
being browsed, loads the batch file and exits; the batch file then loads
the editor, and after exiting from the editor, re-loads FileBrowser with
the edited version of the file.
07
QUIT

This command is used to exit permanently from FileBrowser.
To exit temporarily, use the 'DOS' command. You may also exit from
FileBrowser when in 'Browse' mode by pressing the "Esc" key.

When the QUIT command is given by either method, you will get a new menu
with three options: "Q - Quit without Saving", "S - Save Buffer and Quit",
and "Esc - Return to FileBrowser". The "S" option is especially useful if
you have added highlights to the text - these will be preserved in the saved
file. The text will be saved in a file called "fb.out" in the current
(default) directory.

An alternative method for quitting FileBrowser is to use a 'Ctrl-Break'
interrupt. This causes an immediate exit to DOS. This method can also
be used whenever FileBrowser is expecting keyboard input, e.g. when
entering a file name in 'File' mode, or entering a pattern in 'Search'
mode.
08
INFO

Provides supplementary information about your FileBrowser license.

To get the FileBrowser Title Screen, just type "fb" at the DOS prompt, or
load a file without specifying the '-q' option.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
