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
There are RexExp units available..
What /I/ miss is Perl's pattern matching, and I miss it to the extent
that in some of my own scripting stuff I've implemented it myself:

Free Pascal compiler can do 64 bit but no performance benefits so far ?!
There were never supposed to be any.
64-bit code can, in some specialist cases, be made to execute in about
double the speed of 32-bit code due to the wider registers.
The availability of more registers is another speed

I am developing a GA (genetical algorithm) that needs a large amount of data
to work with.
My development machine has 64 GB RAM and 4 cores.
In that space, I can run simultaneously 4 processes that each use 16 GB of

While I was doing a build, I got the error:

I exited Lazarus, restarted, but now this error appears instead of Lazarus.
Can this be solved without re-installing or rebooting? (It's a remotely

Have a look at TryStrToInt.

Great! - Thanks :-)
Can I simply install the new Lazarus over the old one, and will all the
paths, color settings etc. remain?

I have heard C++ is the best tool for nerds (whatever it can mean). Will

crash me if I ask why should I prefer free pascal than C++ ?
C++ is the best tool for nerds.
Object Pascal is the best tool for professional software developers.
I leave it to the others to get into the details :-)
You can, with FPC, make any kind of software imaginable.
It even supports inline assembly, if you worry about speed.

I was wondering, what exactly is slow in Lazarus, because I use it via
remote desktop over a long-distance WiFi connection and it still is very
fast..?

P.S. I can't recommend Lazarus. It works but it's slow. I use MSEgui.
Some time I'm going to try
