User's Guide - Key Concepts
Variables are special named "containers" for values that change. (The word "variable" comes from the changeable nature of the values that variables represent.)
We say that values are "assigned to" or "stored in" variables. If you picture a variable as a container that can hold a value, assigning a value to a variable is like "placing" that value into a container. You can change this value at any time by assigning a new value to the variable; the new value simply replaces the old one. This ability to hold changeable information is what makes variables so useful.
The "container" represented by each variable is identified by its variable name. At design time these variable names serve as placeholders, marking the places where the values will go once those values become known.
Variable names in AutoPlay Media Studio always begin and end with a percentage sign. Wherever you use a variable like %CompanyName% in your project, the user will see the value that was assigned to the variable instead. (In this case, the user would see the value that was assigned to %CompanyName% earlier in your project, i.e. some text like "Foobar Widgets and Gadgets, Inc.")

Normally, the user never sees the variable names—just the values they represent. (The exception is when a variable is displayed before a value is assigned to it. In that case, the name of the variable is shown where the value would have appeared.) |
There are two kinds of variables in AutoPlay Media Studio: built-in variables, and custom variables.
