I am trying to find a software that can find distance between two ZIP codes.
I think most of them do it by having the longtitude and latidute of each ZIP,
and substract. But this gives the air distance. Where can I find software that
find the ground distance (like in Mapquest).
Thanks,
Joe

In the ISPF editor I am using, for a particullar PO Dataset I am
getting the result of FIND statement narrowed down to the colums
48-56. i.e. if I give "FIND 'TO' ALL", the result I am getting as
"CHARS 'TO' - found 239 times within columns 48 to 56".
Please guide me as to how to make this PDS back to normal so that the
FIND command processes the whole 1 TO 80.
Thank you for the valuable time.

Hi All,
Just a thought, about the find() algorithm in the C++ STL. I read that
the find algorithm can take a range of iterators. If it does not find
the element it is looking for in that range it returns the iterator to
the last element in the range, not to the last element in the
container, to the last element in the range. That being said, how can
we tell if find() has been successful in finding the element we need?
Its easy when we...

I have run into a problem that I cannot seem to figure out regarding a method call to STL map::find(). When the key value can't be found in the map (this is an expected scenario), it returns end() that has _MyValue = unitialized memory (it appears). Thus, the returned iterator is garbage and an exception is thrown eventually. I thought that find() returned the location succeeding the last element in the map if a match was not found. It seems...

I ahve a vector of doubles taht I need to extract values from. I was
just about to use the STL find() algo, but I have a couple of questions:
first: can you specify the tolerance threshold to match on doubles?
second: if yes, how may this be done (i.e. how many one specify the
tolerance threshold for comparing doubles?)

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

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,...
