[Year 12 SofDev] Pseudocode intro

[Mark KELLY]

Hi all. While reading up on Google Docs scripts, I found their introduction
to pseudocode. It's a nice "real world" example of it that kids might
understand.

http://code.google.com/googleapps/appsscript/guide_writing_scripts.html

In case you can't get to it, it reads in part:

Planning a Script

When you're planning a script, you'll find it helpful to write
*pseudocode*first. Pseudocode is a precise and detailed narrative
version of what the
script needs to do. You use pseudocode to help you determine how many
functions your script needs, where you need loops and counters, where you
need variables, and where to perform different calculations. Here's
pseudocode for the stock price script.

first function runs when Spreadsheet is opened

read the current Spreadsheet into a variable
define menu entries
define menu name

second function does most of the work in the Spreadsheet

read the current Spreadsheet into a variable
set the column labels

define a counter called row
start a while true loop
use an if loop to test whether there's a stock symbol in the current
row first column

write data to the log
look up the stock symbol
write the stock information in the correct column of each row that has
a stock symbol
write data to the log
increment the counter

The more detail you put in the pseudocode, the easier it will be to write
the script.
