Exactly right! I'm sorry, my bad.

@Uwe Raabe What am I doing wrong? Why aren't the units grouped by group prefix?

Isn't that the reason you are here? https://quality.embarcadero.com/browse/RSP-28708

Thank you all, you put me on the right track!

You are correct. The code uses expressions like: cx := E or W; grid[ny, nx] := grid[ny, nx] or S;

There is current code, in which I think the use of dictionaries is redundant: const N = $1; S = $2; E = $4; W = $8; var DX, DY, OPPOSITE: TDictionary<Integer, Integer>; // init dictionares DX := TDictionary<Integer, Integer>.Create; DX.Add(E, 1); DX.Add(W, -1); DX.Add(N, 0); DX.Add(S, 0); DY := TDictionary<Integer, Integer>.Create; DY.Add(E, 0); DY.Add(W, 0); DY.Add(N, -1); DY.Add(S, 1); OPPOSITE := TDictionary<Integer, Integer>.Create; OPPOSITE.Add(E, W); OPPOSITE.Add(W, E); OPPOSITE.Add(N, S); OPPOSITE.Add(S, N); // Usage of these dictionaries is shown below in the example code: var nx := x + DX[dir]; var ny := y + DY[dir]; grid[ny, nx] := grid[ny, nx] or OPPOSITE[dir]; To improve performance, I would like to avoid using dictionaries and use a simpler code instead... but I don't know which one? Any help in this arena would be greatly appreciated.

Alas, "Omnia orta cadunt"

Maybe it makes sense to add graphics32 to "Delphi Third-Party" section?

Looks great, is there any chance of animation support (like SVGMagic do)?

Maybe something like https://www.rebasedata.com/convert-interbase-to-sqlite-online ?

OExport - XLSX/XLS/ODS/CSV native Delphi/Lazarus import/export library - https://www.kluug.at/kluug-net/xlsx-ods-delphi.php I use Template engine: automatically process user-defined XLSX/XLS templates.

The latest version is in the attachment. It supports the latest version of RAD Studio.

@Schokohase Thank you, it's works! I wonder if there is another solution? Without creating an extra class?

@Schokohase Sorry, I'm afraid I don't know what you're talking about. What method what class i shoud use? The pipeline does not have an Initialize method.

I have a pipeline for downloading files to a specific database. FFileDownloader := Parallel.Pipeline .Stage(Asy_URLBuilder) .Stage(Asy_URLRetriever) .Stage(Asy_DBInserter, Parallel.TaskConfig.OnMessage(Self)) .Run; procedure Asy_URLBuilder(const input, output: IOmniBlockingCollection); var ovIN, ovOUT: TOmniValue; begin for ovIN in input do begin // ... compose url for downloading output.TryAdd(ovOUT); // url is in ovOUT end; end; procedure Asy_URLRetriever(const input, output: IOmniBlockingCollection); var ovIN, ovOUT: TOmniValue; begin for ovIN in input do begin // ... downloading output.TryAdd(ovOUT); // downloaded file is in ovOUT end; end; procedure Asy_DBInserter(const input, output: IOmniBlockingCollection; const task: IOmniTask); var ovIN: TOmniValue; DB: TxxxDatabase; begin DB := TxxxDatabase.Create(nil); DB.DatabaseName := ??? ; DB.Open; for ovIN in input do begin // ... insert downloaded file in specific database end; DB.Commit; task.Comm.Send(WM_TASK_COMPLETED); end; I run a pipeline for various databases. I need to pass DatabaseName to the third stage of the pipeline. How can I do that? Can I use the SetParameter method of Task controller when creating a pipeline? And if so, how? Any help will be appreciated!
