Range - The Simplest Parameter

Top  Previous  Next

Before we look at how to add parameters and variation to your documents, we need to discuss the simplest parameter - the Range parameter.


A Range parameter is defined like this...


$p = range(2,9)


This command (we will look at how to create this later) creates a parameter, $p, that can range between 2 and 9. Every time you regenerate, $p will take on a new value. Range parameters are the most common way of creating variation for your question.


Let's look at how to include some range parameters into a question.
