Instead of guessing, why don't you first write the program in C and then use the compiler to generate raw assembler code (most compilers have a switch to do this). Then stare at the generated code, compare to yours, and that should solve the problem. Besides, every compiler treats assembler differently. You didn't mention yours. -- Thomas Hruska CubicleSoft President Ph: 517-803-4197 *NEW* MyTaskFocus 1.1 Get on task. Stay on task. http://www.CubicleSoft.com/MyTaskFocus/
