Anyone know a good book on assembly language? http://asm.sourceforge.net/ is a good site. I've used it a great deal in the past. It has references to various Linux's and FreeBSD. > The evolution of programming. Can someone give me a link? I may be one of the missing links <chuckles> I remember writing programs during the late 50's in binary on a form with four columns. Column 1 was to describe the purpose of the step. Column 2 contained the binary code for the step. Column 3 used my own shorthand to illustrate the meaning of the binary code in human language and column 4 described what happened to the contents of the registers. ___________________________ In the early sixties I wrote a small program that translated data rather like the contents of column 3 into contents equivalent to column 2. meant I did not have to remember the binary numbers but only use a consistent set of abreviations. Saved me a hell of a lot of time I can tell you!!! I still had to write the descriptions.. and get the whole lot punched into 80 column cards begore it was of any practical use.
