Need to research {$DUPLICATEENABLE ON} further one day, but surely looks useful but is not really documented, not even at the Delphi 2009 documentation where it was introduced: [WayBack] SysUtils.pfIgnoreDupUnits Constant.

Via: [WayBack] MonkeyMixer has just been updated!- I’ve fixed a unit naming collision with Castlia- I’ve added an XE7 project group (which includes both the BPL and… – Simon Stuart – Google+
PS:
A cryptic G+ comment [WayBack] by Uwe Schuster:
DUPLICATEENABLE is old, but since it is something for IDE packages to avoid intersections with user/3rd party packages there is no need for a documentation. I do use it in an IDE package that did use the JCL/JVCL units as well and does another unit with a common name. IIRC I did mention it related to MonkeyMixer.
I think he argues that documentation is both not needed, but the usage of the directive sometimes is. Which somehow feels like a contradiction to me.
PS2: via Stefan Glienke, an error message that is related to this:
---------------------------
Error
---------------------------
Cannot load package 'Package2.' It contains unit 'Whatever', which is also contained in package 'Package1'.
---------------------------
OK

Any good English books similar to the German [WayBack] Agiles Coaching by Judith Andresen [Leanpub PDF/iPad/Kindle]?
Although my German reading is quite OK, it’s not OK enough to fully use this book.

The new [Archive.is] IDE Fix Pack 6.1 released | Andy’s Blog and Tools is huge, especially for Windows 10 targets:
Windows 10 Creators Update 1703 caused issues with all Delphi programs, libraries and packages because it changed how Windows loads imported DLLs in such a way that it causes performance issues and can crash the debugger.
Delphi 10.2 Tokyo Update 2 fixed this by not producing multiple dll import sections for one DLL anymore.
IDE Fix Pack 6.1 implements that “feature” for all previous Delphi versions (2009-10.1 Berlin) and extends it to not only eliminate duplicate dll imports but also duplicate delay dll imports.
There are also (optional) updates that you can enable with new compiler switches:
- Eliminating
fwait instructions (but be careful, as they can confuse the debugger)
- Optimising calls to virtual methods through interfaces
- Optimising certain function prolog code
There are some smaller changes too.
I’m going to try this soon.

A few tricks to write long strings to files when the Delphi debugger cuts them off (just because they like using 4k buffers internally);
TStringStream.Create(lRequestMessage).SaveToFile('c:\temp\temp.txt')TIniFile.Create('c:\a.txt').WriteString('a','a',BigStringVar)TFileStream.Create('c:\a.txt', fmCreate or fmShareDenyNone).WriteBuffer(Pointer(TEncoding.UTF8.GetBytes(BigStringVar))^,Length(TEncoding.UTF8.GetBytes(BigStringVar)))
They all work form the debug inspector, but they do leak memory. See comments below.

Maybe for my LoT (LAN of Things): having multiple (even many) local LANs some each with their section of LoT equipment nicely separated and partially being able to talk to some of the other LANs or part of the outside world.
Some links that might help me getting this set up:

I did find my Borland Pascal 7.0.1 ISO which showed that https://github.com/romiras/turbo-pascal-archive/blob/master/Files/Dos%20Navigator/FORMAT.ASM is identical to ./BP/RTL/TV/FORMAT.ASM which is used from ./BP/RTL/TV/DRIVERS.PAS to provide this:
{ String formatting routines }
{$L FORMAT.OBJ}
procedure FormatStr(var Result: String; const Format: String; var Params);external {FORMAT};
There are various examples like in ./BP/EXAMPLES/DOS/TVDEMO/ASCIITAB.PAS at line 143:
FormatStr(TempStr, ' Char: %c Decimal: %0# Hex: %0#x ', ASCIIChar);
So it was in the Drivers unit, but also easy to incorporate in your own unit by linking the .OBJ file and providing the external declaration in any unit.
The Drivers unit is very independent of the rest of Turbo Vision: it uses the Objects unit (which most projects use as the System unit at ~500 lines of code provided very little functionality by itself).
For the diskette based install, the .TPU files were on the standard disks and the sources for both RTL and Turbo Vision on separate disks, but anyone would install them as they provided a lot of insight. The CD-ROM has them all on the same medium (both as installers and unpacked in the BP directory).
I just checked Turbo Pascal 6.0 (that I did have a VM for) which has them in the same way.
