In this case == is the bool equivalence operator. It has lower precedencey than <, and >=. "nCol >= nTabStartCol" and "nCol < nTabStartCol + nRowFieldCount" should habe been put into parantheses, to make this clearer. Some compilers output a warning for such expressions because of this. If the compiler is forced to treat warnings like errors, as it is policy in some projects, you may event get en error for this. Yes this is valid code.
