<div>It end to agree with Michael...initializing a value and then a function and algorithms changing the value of that variable. May not hold for a 'constant' as clearly, it stays the same!<br>

<p class="MsoNormal" defanghtml_style="margin-bottom:12.0pt">I've put the SD examiners' comments on the 2011 exam into my post mortem<br>
(<a href="http://www.vceit.com/postmortems/2011sd/SD2011exam.htm">http://www.vceit.com/postmortems/2011sd/SD2011exam.htm</a>)<br>
<br>
In the process I noticed section A, Q9...<br>
<br>
In a program, a line of code that modifies a variable's content is best described as a<br>
<br>
A. function.<br>
B. procedure.<br>
C. instruction.<br>
D. control structure.<br>
<br>
The official answer was A. <br>
<br>
I don't know about this one... I acknowledge the word "best" but still wonder why couldn't the answer equally be an instruction?
<br>
A common instruction like A=0 modifies a variable's content just as often as a function would... more often, probably.
<br>
<br clear="all">
The study design (U3O2 KK09) says kids need to know "processing features of programming languages, including instructions, procedures, methods, functions and control structures" but instructions are not defined by the glossary, the old Fitzpatrick/Keane text,
or Adrian's text (it's not in the index at least).<br>
<br>
What do you regard as an instruction? Trying to get a definition from the internet is frustratingly elusive...<br>
