AppleScript tip: how to assign text to a variable

A question I get frequently is “How do I assign some text (or a string) to a variable in AppleScript?” The syntax for this is as follows:

set myVar to "foo bar"

This assigns the text string "foo bar" to a variable named myVar. A more generic way of stating this syntax is:

set YOUR_VARIABLE to "THE STRING"

If you want to verify this you can make this script a little longer, and display the variable myVar in a dialog, like this:

set myVar to "foo bar"
display dialog myVar
