*******************************
ADDENDUM -- Changes Since Version 5.22
The CMFILER.DOC user manual is current through Version 5.32.
The following features have been added or improved since Version 5.22, in
reverse chronological order:
o Version number changed to 5.32 to avoid confusion with several
versions of 5.31 released to selected users for beta testing.
-----
o The command line support has been expanded to include an
optional path specification(s) to the directory(ies) initially
displayed and an optional initial file mask, as well as an
optional color attribute setting. The command line syntax is
now as follows, where the square brackets indicate optional
parameters: (5.31)
cmfiler [pathspec1[\mask] [pathspec2]] [@color]
where "mask" is a file mask of the form "*.ext", and may be
attached to pathspec1 or pathspec2, and color is C, M, L or T
for standard color set, monochrome attribute set, LCD (except
Tandy) and Tandy LCD attribute sets. Parameters are separated
by blanks. The leading "\" may be omitted from the mask if
there is no pathspec in the command line.
Examples of valid command lines might be:
cmfiler c:\assembly\*.doc c:\pcw\letters @t
CF C:\ASSEMBLY C:\WP51\DOCS\*.DOC
cf assembly @c
cf *.exe
cmfiler d:
CF C:\QBASIC A:\QBASIC /*.BAS
o In the tree module, after the delete commands (D for soft
Delete, Ctrl-D for hard Delete), CMFiler marks the deleted
portion of the image of the tree structure in memory so that it
will no longer be shown on the screen, but does not refresh the
tree structure from disk or update the directory size and files
information. This saves time so that you can do several delete
operations without having to wait for the tree structure to be
reread from disk after each deletion. When you finally want to
refresh the tree from disk after one or more deletes, the
command is Alt-R (for Refresh). (5.31)
o In the tree module, a new text searching function is available
for searching for a text string of 25 characters or less, using
up to eight file filters separated by + signs. Preceding a
file filter with the pipe symbol (|) excludes it from the
search. You may restrict the search to files only in the
currently selected block of the tree (the "painted" structure
in the source panel), or expand it to the entire disk. The
search text entry "*" is permitted, which hits any text (useful
in scanning for several filenames at once in text find mode,
instead of individually in file find mode). The command is
"Shift-F" in the tree module. (5.31)
The screen display in file find and text find modes has been
revised to eliminate the use of blinking to signal the presence
of a "hit". The directories containing hits are shown in high
intensity (underlined in monochrome) with "right arrowheads"
(ASCII character 16) in front of them, and the files containing
hits are shown in high intensity (monochrome underline) at the
top of each file list.
Also, while the results of a text search (Shift-F) or file name
search (F) are displayed on the screen, the command Alt-L
(print tree List) prints a copy of, not the tree structure, but
a listing of the directories containing "hits" and the names of
the files in those directories.
o In the main menu, the function of the tagging options Alt-N and
Alt-O has been changed to "tag all files Newer than the file at
the cursor", and "tag all files Older...". A new tagging
option is added as Alt-D, "tag all files with same Date as file
at cursor". (5.31)
o Esc from the main menu now presents the followup choice of
"Esc to remain in CMFiler, any other key to quit." (5.31)
o A bug has been corrected which precluded running batch files
with command lines. (5.31)
o When shelling out of CMFiler, the DOS prompt has been modified
so that it retains the caller's PROMPT string, and imbeds into
it the string <CMFiler> (CR-LF) so you are reminded you are in
a shell from CMFiler. (5.31)
-----
o The annotation of files backed up with the backup facility
("B") is now that the first character in the extension is the
tilda (~) instead of underscore (_), for readability and to
CMFiler -- Addendum 1-2
ensure that backed-up files always follow the original in an
alphabetical listing. Thus the backed-up file to READ-ME.DOC
would be READ-ME.~DO. (5.30)
o The notes facility was expanded to provide for two cases, and
its mnemonic command changed: (5.30)
- The "edit notes" function has been reassigned the command
"Ctl-N" (was "O"), and its operation is much the same as
modified in version 5.28
- A new "view notes" function is added, as "Shf-N", which
displays the notes in the opposite panel covering the file list
for the target directory, but the cursor remains in the source
panel and all the file services are still available, including
copy and move to the target directory. Toggle out of "view
notes" mode with Shf-N or Esc.
o A display option was added ("Ctl-E" for casE) which lets you
display file lists and trees in one of four possible letter
case conventions: (5.30)
- Files and directories all caps
- Files lower case, directories all caps
- A "modified-Tauck" convention, (eg, Read-Me.Doc)
- Files and directories all lower case.
o In the application launcher, when the command line is shown for
editing just before file execution, you may swap the command
line shown in the window for the last one used in a previous
file execution with Up Arrow, Down Arrow (twice), PgUp or PgDn.
This simplifies multiple execution of the same file with
slightly different command lines, and works with ZIP/UNZIP as
well as user specified applications. (5.30)
o The options screens invoked by Shf-O, Ctl-Enter and Ctl-O were
"spiffed" up. (5.30)
o A separate help screen was added for the edit notes facility,
invoked by F1 or Alt-H from the Ctl-N screen. (5.30)
o The file mask facility was revised to make the method of entry
similar to other data entries, and the default value was
changed from ????????.??? to the simpler *.*. (5.30)
-----
o A logic error that prevented applications launched by CMFiler
from finding the COMSPEC string in the environment was
corrected. (5.29a)
CMFiler -- Addendum 1-3
o Improvements were made to the editor as follows (5.29):
- The record delimiter marks are now toggled with "Alt-
Minus" and the bottom display is toggled with "Alt-Plus". The
current states of both of these switches are stored as the
program startup defaults by "Shf-S".
- The line wrapping mode can be toggled between Wrap and
NoWrap with "Alt-W". If this is done while viewing any but the
first section of a very long file, the editor has to go back to
the beginning of the file to avoid confusion when it
reestablishes the array of memory pointers to the text lines.
The current state of this switch is saved as the startup
default by "Shf-S".
o Wolfgang Stiller's Integrity Master system integrity and virus
checking application generates files named ")(.ID" in each
directory, to record signatures of all the files in the
directory for later integrity checking. It is important that
those not be disturbed, and so CMFiler now has a protective
feature that prevents their being overcopyied. (5.29)
o The Home and End key actions in the main file services memu
have been revised slightly, to make navigation from long
directory lists to long file lists easier. If the cursor is in
a directory list, the first press of End puts the cursor at the
top of the file list, and the second press goes to the end of
the file list. Within a file list, the first press of Home
goes to the top of the file list, and the second to the top of
the directory list. (5.29)
-----
o The file editor is now accessible from the nOtes panel, so you
can take a peek at (or even edit) files while you are looking
at or writing the associated notes. Press Alt-E to Edit, Alt-V
to View. (5.28)
o Tagging files may be done from the nOtes as well. Ctl-T for a
normal Tag (since the letter "T" would be taken as text to be
typed into the note), and Alt-T (as froom file listing screen)
for Alt-Tag. (5.28)
o Improvements have been made to the editor as follows (5.28):
- The algorithm which calculated the display parameter
"Record Number" was not corrected when the line wrap feature
was added. "Record Number" was actually counting the number of
screen lines, and so a record (the material delimited by a
carriage return, line feed or combination) longer than 80
CMFiler -- Addendum 1-4
characters might appear to be 2,3,4 etc., records. That is now
corrected.
- The find-string feature has now been made case-
insensitive.
-----
o The configuration file format for version 5.27 is unavoidably
different from that of the interim version 5.26. Users of 5.26
will have to respecify configuration (F1-F9, Hide and Compare
switch settings, etc.) (5.27)
o If there is old "trash" in the trash can directory
TRASH_CAN.CF, CMFiler only asks once each day if you want to
delete or look at it, rather than each time the drive is
selected. (5.27)
o The "Go to..." commands for navigating within a long directory
listing ("G" to go to a file name in a directory list beginning
with a certain character, "Alt-G" to go to a directory name)
have been expanded. Now you can keep typing the name of the
file or directory you are trying to find, and as you type the
second letter, then third, etc., the cursor moves if necessary
to the file described, until the string of characters you have
typed no longer describes a file or directory name, or you
press Enter or Esc to leave the "Go to" command. The cursor
stays positioned on the last file described by the string you
were typing. (5.27)
-----
o The name has been changed to remove the nuisance underscore
character. In searching for itself and its overlay, it looks
first for CFV if it is the evaluation version, then CF, then
CMFILER. (The evaluation version is identical to the
registration version except that it has an opening screen which
provides a license for 60-day evaluation and information on how
to register.) (5.26)
o You may now edit or view files directly while in the tree
module, without having to exit back to the main module. In the
tree module, press "F" to find files or "S" to show files, and
move up and down the directory tree until you find the
directory of interest. Arrow left or right across to the file
list, move the cursor (dark bar, actually) up or down until it
is on the file of interest, and press "E" or "V", for Edit or
View file. You will be in the editor module directly. Exit
back to the tree module with Esc or, in view mode, Enter. If
you then want to return to the main file services module with
CMFiler -- Addendum 1-5
the cursor selected to this file for editing, printing,
execution, etc., just press Enter again. (5.26)
o Rather than overwriting part of the .COM file to record setup
parameters, which forces the user to reestablish the setup
parameters each time a revision to the program is received, a
separate file is created called CMFILER.CFG (or CF.CFG), which
CMFiler will look for each time it runs. This should be kept
on the same path and be given the same name as the .COM file.
(5.26)
o Logic errors have been corrected to make file moving smoother
for the case where there is already a file by the same name in
the target directory. Previously, this case would cause an
error message "Access denied renaming file", which was not too
enlightening. Now, this case is handled just like copying --
if the target file by the same name is older, it is simply
deleted before the newer file is moved in. If it is newer, the
user is asked to confirm that it should be replaced with the
older file. (5.26)
o A choice of four color pallettes in now available for color
monitors. Press "Ctl-P" (for "Pallette"), then roll through
the choices with the spacebar. Esc to cancel any change, Enter
to change the default color set. (5.26)
o A new option setup menu has been added to permit easy
reconfiguration of a few features. (5.26) It is called by
"Shf-O" (for "Options"), and it presents this menu:
--------------------------------------------------------------------
Move cursor with Up/Dn Arrow. Type option desired.
Define F1 as Help? N
Define "D" as HARD Delete? N
Clear I/O buffers if located? N
Overcopy files with same date/time/size? N
Refresh directory contents after Screen Saver? N
Assign Hidden attribute to NARATIVE.CF file? Y
Monitor (C=Color, L=LCD, T=Tandy LCD, M=Mono) C
Press Esc to cancel changes, Enter to accept.
--------------------------------------------------------------------
These seven "switches" represent setup features that various
users have asked for, but that not all users would want. Any
of the first six may be toggled between Y and N by putting the
cursor on it using the Up/DnArr keys, and pressing the
spacebar, or pressing Y or N. The seventh must be set for your
CMFiler -- Addendum 1-6
monitor type by pressing one of the key choices. Once you have
reconfigured the way you wish, press Enter. Esc exits with no
changes. Here is an explanation of each feature:
1. The F1 key has been added as a Help call in the editor and
tree modules, and can be so designated for the main module by
resetting this switch to Y. The sacrifice is loss of F1 as a
user-defined application.
2. For those who do not wish to use the "soft" delete feature
nor be bothered with the directory "CF_TRASH.CAN", the "D" key
may be reconfigured to "HARD Delete", identical to "Ctl-D" by
resetting this switch to Y.
3. The I/O buffer clearing feature for data security during
file writing operations runs into problems on some system
configurations with DR DOS 6.0 as the operating system. It has
been set to a default mode that does NOT clear buffers before
writing. If you want to invoke this security feature, you have
to reset this switch to Y.
4. In the default setting, CMFiler does not waste time during
file copy operations overcopying any file in the target path
that are reported by DOS to be the same date/time and size as a
file in the source path. However, sometimes you might want to
mass-overwrite files on a backup directory or disk that are
suspect, even though they may appear to be identical. Just set
the Overwrite switch to Y.
5. For Windows users, if you run CMFiler in a window, it does
not have any way of knowing when it returns to the foreground
whether any other application has written to the directories
that it is selected to. In the default setting, it does not
refresh the file listing (reread the directory tables).
Windows users may want to reset this switch to Y.
6. Users have asked to be able to specify that the
NARATIVE.CF file, containing the file/directory notes, not be
assigned the hidden attribute. This switch may be reset to N
for this purpose.
7. CMFiler can detect the presence of a true monochrome video
card, and when a monochrome card is present, there is only one
color set available. However, when CMFiler detects a color
card, there is a range of possibilities. The attached monitor
may be an LCD or monochrome monitor, in which case a set of
default color attributes designed for a CGA/EGA/VGA monitor
would be awful. On initial execution, CMFiler establishes what
type of monitor you have atached by forcing a choice. This
setup option lets you change that initial choice if you wish.
CMFiler -- Addendum 1-7
o CMFiler now does a rudimentary self-check for integrity each
time it loads. If the file has become corrupted by tampering
or a disk sector gone bad, you will get a message to that
effect and the program will offer you the option of continuing
or terminating. This will detect some of the file-infecting
viruses, as well as corruption by editing or defective media,
but should NOT be counted on as an anti-virus measure. (5.26)
[There is no substitute for a good virus checking/integrity
checking software suite. I recommend the shareware program
Integrity Master by Wolfgang Stiller.]
o A new "Save configuration" command has been added as "Shf-S" to
make saving the current configuration (Hide switch, Compare
mode switch, file Order mode, etc.). This saves all the
current setup data to the .CFG file. (The Options command at
"Shf-O" also calls the same save routine when it exits, so you
do not need to press Shf-S after Shf-O.) (5.26)
o The spacebar has been remapped to tag files. The date/time
display is toggled with the "5%" key. (5.26)
o The editor module has been revised to wrap lines longer than 79
characters, so that there is never any information off-screen.
This makes viewing .COM and .EXE files much easier, and has
little effect on edited text files. This is a display feature
only -- the editor does not insert line delimiters in the text.
(5.26)
-----
o The on-screen Help in the main module has been reoganized for
clarity. (5.25)
-----
o A new file copying option, "copy with rename", has been added
as the command "Alt-R" in the main file services module. It
operates only on the file at the cursor. (5.23)
CMFiler -- Addendum 1-8
