DLSupC32, DLSupC16, DLSupCX, DLSupCTW, DLSupCBF, and DLSupCBT
Comparison and Summary

DLSupC32 and DLSupC16 are, relatively, simple to use and are
deliberately aimed at the single file pair text line processing.  They
contain the basic components for the entire line of the DLSuperC
family.  They, also, should serve most users' text compare
requirements.

DLSupC16 is a holdover from Window's 3.11 days.  It is a stable
product and no extensions are planned while DLSupC32 is a more
evolving vehicle.  Even though DLSupC32 currently has a fully
functioning set of capabilities, it should be extended, periodically,
to include more functions in an attempt to increase a programmer's
problem determination productivity.

DLSupCX is not as simple to use as DLSupC32 and is aimed at the more
complex task of comparing commonly named files from two file
directories with a single interactive invocation.  However, DLSupCX
can also be used to do a single text file pair processing as DLSupC32.
The same results should be obtained.

There have been several added capabilities to the single file pair
processing in DLSupC32 that are not in DLSupCX.  Namely, Part Compare
of a file, Unordered List Comparison, Batch invocation and the listing
of up to 2048 character records in Batch Moded are these extra
capabilities.  Many will probably not be implemented in DLSupCX as
DLSupC32 remains the best environment for doing these special items.

DLSupCBT is similar to DLSupC32 with two exceptions.  It provides for
comparing files at the byte level (versus a text line) and it has the
capability for running batch jobs, as does DLSupCRV.  The presentation
of DLSupCBT is in the form of a hexadecimal dump with the printable
characters shown of the same line of data.  DlSupCBT has several
preference options one which allows the user to do a part comparison
of a portion of the two input files.  The DLSupCBT is a special
variation of DLSuperC that can be done on all file types but it
details differences at the lowest byte level.

DLSupCRV is also very much like DLSupC32 but without input text
filters.  It, also, flags all changes even lines that appears to be
visually identical.  An example would be lines that have blanks that
might be truncated in one file but not in the other.  Another case
would be a null line in one file visually appearing identical as a
full line of blanks.

The DLSupCRV program is designed to be a tool to be used, primarily,
in a source library maintenance environment.  It can generate both a
"Delta" and an "Undelta" file.  It, also, generates full lines of
source in its delta output and has the added capability of processing
Fixed Length Records (i.e., all data records are equal and no CRLF is
needed at the end of each fixed length record).

DLSupCTW is the lastest addition to the DLSuperC family of compare
program.  It features comparison at the word level.  DLSupCTW extends
the capability of DLSupC32 by first partitioning files into text lines
and these lines into word tokens.  It compares the word tokens for
matches and reports on the changes as a combination of changed lines
and words.

The program's greatest advantage is that in handles long text input
lines and displays the word so the user can see where in the line the
changes has occurred.  Entire lines are displayed by generating
composed lines with word wrap and using up to three lines spaced so
insertions and deletions appear under the matched point in the
original input line.  Word compare inspects adjacent lines for matched
words whereby the best comparison set between the two files is found.
It is not affected by line reformatting or added blank or comment
lines.  Html, Bat, Ini, and even program source files are candidates
for this new change detection.

DLSupC16, DLSupC32, DLSupCX, and DLSupCTW are separately purchasable
shareware download compare programs.  Each are offered at $29.95.
Each is aimed at the text line (or word and byte) compare environment
and allow auditing personnel to audit data files for changes.

DLSupCBF (DLSuperC for Binary File Directory Compare) - another member
of the DLSuperC family is similar to DLSupCX in useage and degree of
complexity.  DLSupCBF is aimed at comparing directory files at the
binary-file level and should be faster and produce results expected of
more traditional directory compare operations that inspects files to
determine where the differences exists.

The user may appreciate the speed of the file level compare (versus
the full line compare) when many file compares are attempted.  The
significance of the overhead involved in the complete compare of a
directory should not be underestimated.  File compares return only if
a file matches or not.  There is no requirement to determine where or
how the file differ.

The advantage of comparing included subdirectories within the initial
directories is an added feature found in few, if any, directory
compare programs.  Several users have used DLSupCBF to verify a newly
created CD against the original version.  This is a special case of
comparing two directory nodes and all included subdirectories where
the two directories are defined as with two different device
addresses.

DLSupCBF is offered at $21.95.

DLSupCBT can be registered for free ($00.00) with no strings attached.

Shareware Considerations

This is an announcement for the Shareware versions of the DLSuperC
family.  These programs are not meant to be free.  They can be
downloaded and used, normally, for a trial period of 30 days.  Please
try them out and see whether you agree that - "DLSuperC is the best
set of compare programs you have ever used".

Note:  The bookie man won't come and get you just for looking and
trying.  Yes, sometimes it takes longer to evaluate a program and
decide whether it is worth registering and become legal.  So, I've
made it relatively easy to test drive any of downloaded programs.  All
unregistered programs have a trial popup panel displayed prior to
execution and only an unregistered notice appearing on top of the main
panel during program execution.  The trial popup panel will disappear
after registration and a user or company name will appear in the
registry notice on the primary panel.

The complete capability of each program is at your disposal in all the
trial versions.  Registered users retain their registered status for
all, subsequent, downloaded upgrade versions.  A registration invoice
file with more details will be included in the registration package.

To repeat, the Shareware price for DLSupC16, DLSupC32, DLSupCX, and
DLSupCTW is a paltry $29.95.  DLSupCBF is priced at $21.95 for each
copy installed.  Site licenses (i.e., 10(10%),20(15%), 40(20%),
50(25%), 100+(30%) copies of one registered product at one site) are
allowed to be purchased at a discount rate.
