Anyone who pretends to know how to use computers effectively
must know how to use grep. (grep is available for Windoze.)
Let's say that you want to search all of the files in the
current directory for lines that contain "foobar" or
"foo bar" or "foo-bar", followed later in the line by
"practise"

4. RegExes, especially complex ones, are usually orders of magnitude
slower than straight Pascal, because they're usually interpreted at
runtime by a parser.
They could possibly be preprocessed if assigned to a constant, although
I've not tried doing this.
If you modify the RegExp-parsing so

I agree with Jürgen.
It's is much more preferable to write standard Pascal, for many reasons:
1. The number of people proficient in RegExes is very small, and it takes
regular practice to keep the skill up.
Very bad to be dependent on such a subset of Pascal programmers.
2. RegExes are notori

It looks for a date pattern like the follow
10/10/08 and 10/10/2008 with space and then some other chars as well.
I think if it was with boundaries of begin and/or end (^ and $) it would
work even better.
The () indicates groups. each group is the string extracted from the
pattern, and can be us

Your regex is awful :)
Why not to write it as follows (ruff rewrite):
IF cells[2, dateTime] = m|((\d\d)/){2}(\d{2,4})\s.*| THEN BEGIN
Anyway, I'm not sure how good idea it will be to have it part of the syntax.

Not only do I have no idea what the above code does, I have no desire to
find out! Talk about cryptic.
