MASM has a number of built in operators that allow a programmer to use C style evaluation and loop code when writing high level Windows code that interfaces with the operating system.



More often than not, low level algorithms do not use any of the high level operators as it would produce suboptimal instruction sequences for maximum performance but much of the high level code inherant in Windows suffers from complexity rather than speed considerations and it is here where the C style high level emulation code provides its biggest advantage.
