Hi all
I've written a python program that adds orders into our order routing
simulation system. It works well, and has a syntax along these lines:
./neworder --instrument NOKIA --size 23 --price MARKET --repeats 20
etc
However, I'd like to add a mode that will handle, say:

Hello all,
I am puzzled by the term 'semantics' !
Well I know about 'syntax of a language' - as defined by its
associated grammar
Then what is this semantics?
What does the C Compiler checks during semantic analysis?
And does it produce error OR warnings when it encounters a semantic
mistake?

Hello,
I have a question about the correctness of the language grammar for the C#
2.0 specification. I am working with the grammar specified in the June 2005
ECMA-334 standard.
Basically, a using-namespace-directive is defined as follows:

using namespace-name ;

in March, i posted a essay “What is Expressiveness in a Computer
Language”, archived at:
http://xahlee.org/perl-python/what_is_expresiveness.html
I was informed then that there is a academic paper written on this
subject.
On the Expressive Power of Programming Languages, by Matthias
Felleisen, 1990.

On modern 32-Bit PC's, the following setup is common:
char: 8-Bit
short: 16-Bit
int: 32-Bit
long: 32-Bit
"char" is commonly used to store text characters.
"short" is commonly used to store large arrays of numbers, or perhaps wide
text characters (via wchar_t).

Hello,
I have recently had to deal with an XML-based
programming language. (The programs are
generated programmatically.)
XML leads to a "two-level" parsing problem: first
parse the xml into tokens, then parse the tokens
to grasp their meaning (based on the semantics
of the programming language).

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
