Still a lot of confusion over the \u00a0definition of a function and procedure in Higher Computing Science and how they differ.<\/p>\n

A procedure is a sub program\u00a0that\u00a0contains a block of code. It uses parameters to pass data to and from the main program.<\/p>\n

A function is a sub program that contains a block of code. It uses parameters to get data from the main program and passes back a single piece of data using\u00a0RETURN.<\/p>\n

In the program below you can see a procedure called calcArea and a function called funcArea. Both of these sub programs do the same thing but they way the work is different. The last two lines of code could be merged into<\/p>\n

MsgBox(“Function Area =” \u00a0& funcArea(10,11))<\/strong>.<\/p>\n

The procedure is always called on it’s own. Can you name another function shown in the program below?<\/p>\n
