Subject: LPT1 and LPT2 in 1 program

Hi Franz,

Thanks for your valuable help.  I took your suggestion and it worked
perfectly on the machine with the software and two printers installed.
Much appreciated.
I now have to discover how to get a second machine accessing the host to
perform the same function.  The networked machine chokes with error '160
Device Write Fault' trying to write to LPT2.  I'm fiddling with Win95
hoping to discover the secret.
Thanks again
Peter

Yeah, ofcourse.. I am currently writing a small racing-game with
scrolling screens, and I need a big tracks to be loaded into memory.
Naturally I must divide them into smaller 64k chunks instead ? The
conventional memory will not be enough though. Guess I will have to use
XMS, any tips/hints ?

Dear Fellow Pascal Users,

Please let me try to help by repeating the central information about the Pascal newsgroups' organization. This information is an edited rendition from our

 132960 Dec 13 1997 ftp://garbo.uwasa.fi/pc/link/tsfaqp.zip
 tsfaqp.zip Common Turbo Pascal Questions and Timo's answers

I think it will be advisable that I post this information automatically once a week to all the pascal newsgroups to help to keep us organized.

76. *****

 Q: What are the current Pascal newsgroups on the Usenet news?

 A: The following new Pascal discussion newsgroups were created June 12, 1995 to replace the old comp.lang.pascal. The new Delphi newsgroups were first created around July 10, 1995. Further Delphi newsgroups were added in April 1996.

A special note about Delphi postings. Please use the delphi newsgroups for the Delphi related postings. In particular, the newsgroup comp.lang.pascal.borland is _NOT_ for Delphi related
subjects!

A second special note. Please avoid crossposting between the newsgroups. In particular do not crosspost between the old and the new newsgroups. It slows the transition to the new system. (This automatic posting breaches the general non-crossposting tenet only because it is relevant information about the arrangements of all the newsgroups involved.)

CURRENT:
 comp.lang.pascal.ansi-iso Pascal according to ANSI and ISO standards.

Please duly observe the good netiquette in the Pascal newsgroups. For example, please note that, while posting source code snippets of reasonable length is welcome, you should not post binaries or binary attachments (uuencoded, mimed, base64:d, etc) to these newsgroups. If you have such material to show or share please make it available at an FTP or WWW location and post only the pointer.

This will be a view from 50,000' of some popular sorts.
Hopefully, the names will be accurate enough for you to find additional details if needed. Except where designated otherwise, "list" is used in the generic sense and does not mean a linked list.

BUBBLE SORT (also called exchange selection sort, propagation sort) Propagating from the top or bottom of the list, adjacent elements are swapped if out of order. This continues until no elements are swapped. This is one of the slowest methods but, when your list is short, it is fast enough.

INSERTION SORT (roughly twice as fast as Bubble sort)When linked lists are used, this is a popular method. Sorting is done like sorting a hand of playing cards, picking up one at a time and placing it where it is ranked.

EXCHANGE SORT (n! comparisons)
Suppose you are sorting a list in alphabetic order. You start with the first item and traverse the list to find the smallest. If the smallest is not the first item, swap items. Now you start with the second item and find the next smallest, etc. Easily remembered and implemented with two loops, one nested.

SHELL SORT  (Due to Donald Lewis Shell, circa 1959)
Because of its age, this method has gone through so many changes while still keeping the same name, its history is confusing. In general you start by comparing the first in the list to one a fixed distance down the list. If these two are out of order, swap. Move both comparison points down one position...and so on to the bottom of the list. If any swaps were performed, start at the top with the same separation distance and traverse the list again. Keep doing this until no swaps are made.

Shrink the distance between the comparison points in some algorithmic way and do it all over again. The very last comparison run has the exact look of a single Bubble sort run BUT the distance to move the out of order elements is short.

Originally, the Shell sort used separations of either 8-4-2-1 or  7-5-3-1. For long lists this does not move the out of order items far enough. Most implementations today start by comparing the first item with the item half way down the list. When no swaps are made in a pass, the comparison point's separation is halved and so on.

There are other modifications that make this sort almost as fast as the Quicksort and FASTER than the Quicksort on partially ordered lists.

QUICKSORT (Due to C. A. R. Hoare, circa 1962) The most popular implementation uses a method which keeps calling itself (recursion). This places it in the advanced section of most textbooks. However, because of its speed in sorting truly randomly ordered lists, it should be in anyone's sorting vocabulary. This is a "divide and conquer" technique. The "key" (pun intended) to this method is to be able to locate a sorting key for each pass.

Given a sorting key value, the first pass places values higher than  the key on one side of the key and those lower or equal to the key on  the other. The sublist higher than the key gets a new key and does the same as does the sublist below the key. Finally when all these smaller and smaller pieces are sorted, they are reassembled in a complete sorted list. Worst case for this sort is a mostly sorted list. Another limitation may be encountered--you run out of stack space due to the recursion.

HEAPSORT
Assume we want the largest on top. First the data are arranged in a type of binary tree called a heap. Each element of the tree has a maximum of two smaller or equal valued descendants which are arranged in a predetermined way, depending on their values. The order of the values on the tree allows the rapid placement of new values. It also allows the tree to be traversed rapidly to "pluck" the leaves into a sorted list.

Subject: Problems with Protected Mode Programs

Newsgroups: comp.lang.pascal.misc

Since the crashes do not occur if you are debugging with TD, it might be
helpful to know that TD initializes the data segment (I believe) and the
stack segment (guaranteed) with zero byte values so all global and local
variables are init´d to zero, and that does not happen if you have no
debugger running. Thus, in stand-alone sessions, your app my choke because
of a dangling pointer reference, or other uninit´d variables consequences.

The format changes depending on the driver. There is no standard definition
for the format of the image. Anyone that creates a driver is free to use
whatever format they wish.

What is consistant is that the first word is the Width in pixels, the second
word is the height in pixels. The following words are the packed image data,
followed by a garbage word at the end of the image.

For monochrome, generally the data is packed one bit per pixel left to right.
It may or may not contain extra pixels in the X direction to fill out a byte
at the end.

For EGAVGA, it depends on the version of the driver and whether it is a 3rd
party driver or not. The older drivers used packed nibbles to represent the
pixels, some of the later versions use four rows of X data to contain the scan
line for each color plane. Repeating for the number of Y scan lines saved.

For 256 color drivers, usually data is saved one byte per pixel left to right,
top to bottom.

Sounds like what you need is my unit which adapts Boyer-Moore to file
searching.  It's pretty quick.  It's on my code page, but a quick link to it
is:

http://www.netcom.com/~setech/download/bmsearch.pas

BTW, when doing large block transfers, it's best to use values which are
multiples of 1024 based on 2^n:  1024, 2048, 4096, 8192, 16384, and 32768 are
the best numbers to use.  When you get away from these file sizes, you get I/O
fragmentation which can cause sectors to be re-read and re-written -- may not
make a difference with small files, but with large files, it will create an
unneeded bottleneck.

This is a bit misleading.  CL contains the sector number in the lower 6 bits,
but the upper 2 bits may be used for extra cylinder bits (on hard drives).
Also, drive numbers don't have direct correlation to the sequential ordering
used by DOS calls.  Removable media drives (particularly floppies) will be
numbered 00h, 01h, 02h, etc.  Fixed drives will be numbered 80h, 81h, 82h,
etc.

> [snip!]

Frankly, a better idea is to avoid direct I/O via int 13h (especially because
it can cause problems under Win95) and use int 21h, AH=69h (get/set disk
serial number).

>From Ralf Brown's Interrupt List:

Inp.:
        AH = 69h
        AL = subfunction
            00h get serial number
            01h set serial number
        BL = drive (0=default, 1=A, 2=B, etc)
        BH = info level (00h only for DOS; OS/2 allows other levels)
        DS:DX -> disk info (see #1455)
Return: CF set on error
            AX = error code (see #1366 at AH=59h/BX=0000h)

I have an even simpler approach :

image1.autosize:=true;
image1.picture.loadfromfile(..);
image1.width:=image1.width*2;
image1.height:=image1.height*2;
image1.autosize:=false;
image1.stretch:=true;

Depends on the controller actually. Of course, a good bet is Adaptec and ASPI
nowadays.

A very good reference

The SCSI Bus and the IDE Interface, Protocols, Applications and Programming by F. Schmidt
ISBN 0-201-42284-0

It includes useful pascal source.

A year ago I asked the very same question. Did you try to search www.dejanews.com? okokok here's the solution..have fun with it:

function MakeLongPath(ShortPath:String):String;
var PIDL:PItemIDList;
    szPath: Array[0..MAX_PATH] of Char;
    olePath: Array[0..MAX_PATH] of WideChar;
    chEaten,dwAttributes: Longint;
    Buffer:Array[0..Max_Path] of Char;
begin
 Result:=ShortPath; //If not succeed then return ShortPath
 StrCopy(szPath,PChar(ShortPath));
 If CoGetMalloc(MEMCTX_TASK,OLEManager)=S_OK then begin
  If SHGetDesktopFolder(PDeskTopFolder)=NOERROR then begin
   if MultiByteToWideChar(CP_ACP, MB_PRECOMPOSED, szPath, -1,
olePath,MAX_PATH)<>0 then begin
    If
PDesktopFolder.ParseDisplayName(0,nil,olePath,chEaten,PIDL,dwAttributes)=S_O
K then begin
     If SHGetPathFromIDList(PIDL,Buffer) then Result:=Buffer;
     OLEManager.Free(PIDL);
    end;
   end;
   PDesktopFolder._Release;
  end;
  OLEManager.Release;
 end;
end;

The following procedure will sort an array 'a' of integer from 0 to size-1 (size elements) using the shellsort algorithm.

>------------------------------------------------<
procedure shellsort(size:word);
var
  temp, gap, i, j : integer;
begin

  gap:=1;while (gap<size) do gap:=gap shl 1 + 1;

  while (gap>1) do begin
    gap:=gap shr 1;
    for i:=0 to size-gap-1 do begin
      j:=i;
      while (j>=0) and (a[j]>a[j+gap]) do begin
        temp:=a[j];a[j]:=a[j+gap];a[j+gap]:=temp;
        dec(j,gap)
      end
    end
  end

end;

Does anyone know if there's a patch or something like that ... Or what program can I use for dissamble under Win95 ????

I don't know if this is useful, but D2 has a "disassembly view" built in, but hidden. (D3 has it too).

I don't have D2 installed anymore, but from memory you have to do the following:

Run RegEdit and locate the Delphi 2 key (\Software\Borland\Delphi\2.0).

Add a new string key called "EnableCPU" and set the value to "1" (one).

Restart Delphi, and I you should find a new commmand on the View menu.
