Dugal) Organization: CACS, Univ of SW La, Lafayette, LA Lines: 17 A few years ago I implemented a number of routines to handle long integers in Turbo Pascal. I was inspired by similar routines for the 8080 published in Dr. Dobbs' 9 years ago, and found it to be an excellent way to learn 8086 machine language. I have not posted them because they manipulate the integers a byte at a time, and I learned later that I should have used a word at a time, thereby achieving a 2x speed improvement. I haven't gotten back to rewriting the routines, and may never! If you get no better offers, let me know and I'll see what I can to about providing what I have. My goal was to implement the RSA crypto algorithm; it turned out to work, but verrrrry slowly. -- -- James Dugal USENET: ...!ut-sally!usl!jpd Associate Director CSNet: jpd%usl.edu Computing Center US Mail: PO Box 42770 Lafayette, LA 70504 University of Southwestern LA.
