This works for r1mach, and in general if the constants are given in human-readable form, but I have seen d1mach in which the constants were given as two 32-bit hexadecimal numbers. In that case, you have to worry about byte ordering, i.e. you may have to reverse the two hex numbers between one machine and another. -- Fritz Keinert phone: (515) 294-5223 Department of Mathematics fax: (515) 294-5454 Iowa State University e-mail: keinert@iastate.edu Ames, IA 50011
