On this page, there are links to some short assembler code examples. Please note that much more information and code examples can be found in the article Considerations for writing and using Intel assembly code in Delphi projects, which has recently been reissued as completely revised second edition. Feel free to send me your remarks or tips about these pages and the other Delphi-related content you can find here. All code examples open in a new window.
