program Portscan;
(*
  1.10d - Okay, upon request the whole file moves out of the EXE again to be
          able to customize the port descriptions ;)
  1.10c - now the programmer can optionally include the short names for the
          ports as string table resource using the PORTNAMES compiler switch.
          (A Perl script in the \SOURCE directory can be used to extract the
           names. Just put a file called "port-numbers.txt" into the directory
           and then execute the .CMD file to extract the names - get the file
           from: http://www.iana.org/assignments/port-numbers)
  1.10b - can be minimized to tray now by double clicking the caption
  1.10a - small enhancements
  1.10  - sports new scheduling scheme. Thanks to Hagen for pointing it out to me.
  1.00  - initial release

  The program can definitely be compiled with Delphi 3 through 5!

  The program will start and maybe run on Windows 9x. But when reaching a limit
  of 32K items in the listbox it will hang or whatever. I don't know. I just
  want you to notice it. It's a limitation of Windows 9x I am not willing to
  work around, since Windows 9x hopefully will disappear from PCs soon.
