Thanks Instructor.
Now, "\0" generates a syntax error, so it's OK.

\Z
- it seems to me that it works well.

There is a problem with \A anchor:
\A
- matches to the border between any characters and to the end of the text:
\A.
- matches any single character.

In the new test version does not have changes that you have entered yesterday ("\0", "\0+", "\0*", "\0{2,}"): http://akelpad.sourceforge.net/forum/viewtopic.php?p=21420&highlight=#21420

I found still these bugs:
\Z - also matches "Z" character,
.\A - also matches any character plus "A" (eg: "BA", "CA").

Thank you very much, now everything is OK.

In AkelHelp-Eng.htm:
- description of expression "(?<!pattern)" is truncated,
- You can add that "\z" is equivalent "\Z".

The following two regular expressions work in different ways:
\w+(\W*)
\w+\W*
In the first regexp, the "+" quantifier is lazy (non-greedy).
In the second, the "+" quantifier is greedy.

However, you may need to implement two types of quantifiers:
- greedy: ?, *, +, {n1,n2}
- lazy: ??, *?, +?, {n1,n2}?

I need to replace the first and last character in the text on "x".

If:
\A - matches the position at the beginning of the search range,
\Z - matches the position at the end of the search range,
in the previous test version it worked well.

In the new test version it is inconsistent.
In the above example, regexp matches 9 times (8 times "b" and 1 time new line), and replaces only 2 times.

I propose to add two new anchors \a, \z (or change the way of working \A, \Z), so that:
\a - matches the position at the start of the text,
\z - matches the position at the end of the text.
"\a" should match only the beginning of the text (only once), like "^" matches only the beginning of the line (only once, if there is one line).

It seems to me that this is a well done in SynWrite: http://www.uvviewsoft.com/synwrite/
