Improvements and Fixes

This release is better than previous sets of PentaTextTools:

The MAXIMUM pattern and data size for GREPPES has been
increased.  PDGREPPE can have many more definitions, larger
pattern size and increased use of magic pattern terms.

All Text Tools have greater safety via pointer checking.

Options Added:

See file CHANGES.LOG

These tools, like almost all others, are NOT perfect.

However they are close to what could be called a final release
version.

If You report bugs we will report the items
improved or fixed here...

Problems:

START of Pro Peter's Great Bug Report

I just tested 15 freeware text search utilities
and your programme is the best.  I have only used
fgreppe because I did not have the time to look
at pdgreppe.

I FOUND 3 OR 4 BUGS:

1.

The -kF parameter (lfn handler) prevents the -kf
(write to protected files) parameter from working.

I.S. Note: This and some related problems improved.
Applies to FGREPPE PDGREPPE NLX.

2.

With the -S parameter (summary)

- if the -kR parameter (rescan files when shortened) is used

and

- if some files are shortened, then

the shortened files are added twice to the big
files total of the summary.

I.S. Note: Improved
Applies to FGREPPE PDGREPPE

3.

With the -S parameter (summary), the results

- Lines Searched=x and

- Lines Met Criteria=y

sometime seem to be wrong.

I did not investigate further because, for what I
was doing, this part of the summary was not
important.

But there is probably a bug.  You may want to
investigate.  I used a files sample which
included both text and binary files.

I.S. Note: Improved
Applies to FGREPPE PDGREPPE

4.

The Microsoft bug:

When the programme pauses and wait for a one key
input from the user (it says Press key, Quit
is...) the 4 arrow keys must not be used to make
the programme move forward.

If one of the arrow keys is used, then something
stays in the keyboard buffer and prevents the
programme from pausing at the next pause.

This is not a bug from your programme, it is a
bug from Microsoft.

I know it because it happened to one of my
programmes in 2001.

I easyly canceled the effect of this bug by
adding a line of code which cleared the keyboard
buffer just before pausing for an input from the
user.

I.S. Note: Improved
Applies to ALL TextTools

END of Pro Peter's Great Bug Report

5.

Command did not work on Windows NT with an error message of

"The system cannot execute the specified program."

Solution:

This is because the command line went BEYOND 127 characters in
total length.  Try using a shorter command line or the option
"-jF<d>" that can extend the command line.  Or try using the
<PROGRAM>_OPTIONS environment variable to hold DEFAULT values
for each command for a Text Tool.

6.

PDGREPPE was too slow for searching at start or end of files
or if file size was not adequate for search.

I.S. Note: Improved
Applies to PDGREPPE

*****

Note:

Every set is given THOROUGH testing prior to release but
sometimes an error slips through.  We take special care to
investigate and correct any problem areas.
