You’re more than welcome to grab INT64.INC (using NASM) from V8Power Tools [1]. Or, you could port the functionality to a different assembler. It has a bunch of macros for handling 64-bit numbers on 8086. It also does addition, subtraction, multiplication and division on 64-bit integers. Plus, it provides other macros and bitwise stuff like OR, AND, etc. It was my first attempt at pulling off big number crunching using only 8-bits and is a little rough around the edges. But, it definitely does work. I’ve made a lot of improvements to performing big number math since that was written. For example, my previous version of DOSKIT simply (LOL) extends the 8086 to support 64-bit numbers and pseudo registers. The LazyBoy library (aka DOSKIT v4.0) makes the prior version look simplistic and primitive. It will handle numbers from a BYTE to a ZWORD. It also can be compiled to target processors (like 386) to reduce the code required to handle those large numbers. But, that library is a work in progress. Unfortunately, using the DOSKIT math stuff is an all or nothing thing. You can’t just pick the math out of the library. It requires using the whole library. :-) Jerome [1] https://github.com/LoopZ/V8Power/blob/master/SOURCE/INT64.INC > > > > > _______________________________________________ > Freedos-devel mailing list > Freedos-devel@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/freedos-devel
