Here's a proposed Q&A for the FAQ based on a couple recent
threads. Appropriate comments appreciated
X.Y: Why doesn't Python have macros like in Lisp or Scheme?
Before answering that, a clarification on what 'macro' means.
A Lisp macro is a way of modifying code when that code is first
defined. It can rearrange the structure of the code, and add and
remove parts of it. Unlike C's #define macro language, Lisp
macros understand the...

I think everyone who used Python will agree that its syntax is
the best thing going for it. It is very readable and easy
for everyone to learn. But, Python does not a have very good
macro capabilities, unfortunately. I'd like to know if it may
be possible to add a powerful macro system to Python, while
keeping its amazing syntax, and if it could be possible to
add Pythonistic syntax to Lisp or Scheme, while keeping all
of the...

In Access 95/97 I used to be able to create pull down menus (File,Edit
...) from a macro. It seems there used to be some wizard for that.
However in Access 2000 it seems you have to build your menus by
customizing a toolbar. With this method you have to create a separate
macro for every single menu and sub menu. The old method would allow
me to include several menus (File/ print/ page setup ...) all within
one macro. Now it seems I...

Where should I use them?
I am giving you my understandings. Please correct me if I am wrong:
MACRO:
e.g.:#define ref-name 99
The code is substituted by the MACRO ref-name. So no overhead.
Execution is faster. Where will it be stotred?(Is it in bss/stack/?)

Hi all.
Is it possible to pass the whole blocks of code (possibly including
" and ,) as macro parameters?
I want to do something like:
MACRO(FOO, "Foo",
"return "Foobar";",
"foo(); bar();")

Dear NG,
Can someone assist me with writing the little code that is needed to
run an update table query each time the database is opened? From what
I've been able to glean from this group, the Autoexec Macro looks like
the way to go. Could someone please assist?
Thank you very much!

Hi,
It is benifitical to use macro in certain cases.
http://www.boost.org/doc/libs/1_35_0/libs/preprocessor/doc/index.html
However, I found that it is not easy to debug a macro. For example,
for the following program, I can not trace into the last macro in gdb.
In this sense, if I want to debug the code easily, should I avoid

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,...
