Using Assembly language for the implementation of your ideas is fun (I surely have said that already and, probably, even more than once). However, it may become quite annoying when it comes to certain operations, which have to be re-implemented in different parts of your program. One possible solution may be implementing those operations in the form of a procedure and calling it when needed. However, this may quickly become a nuisance as well, once you have a procedure; which receives more than zero parameters. While in high-level languages you simply "pass" the parameters to a function, in Assembly, you have to actually pass them to a procedure in accordance with the calling convention of your choice, which, in turn, may imply additional headache with management of registers (if parameters are passed via certain registers) or accessing the stack....
