Question

Quizplus · Accepted Answer

ByRef is the keyword in Visual Basic used to pass reference to a variable instead of passing the value itself. Passing a reference to a variable allows modifications to the original variable inside the method or function. The other options mentioned, ByVal, ByArg, and ByInd, are not valid in Visual Basic syntax. Instead of simply providing the answer, it would be better to encourage the colleague to use available resources like reference texts or search engines to find the answer themselves and develop their own problem-solving skills.
