B.1. Data Types
AppleScript and HyperCard can both handle a variety of data types
(strings, numbers, and so on). However, both languages have a
different way of checking what kind of data is
stored in a value or variable.
In HyperCard, if you want to check what
kind of data something is, you use the command is
a, like this:
if 4 is a number then
--Do whatever
end if
In AppleScript, you use the
class keyword to accomplish the same data
checking:
if (the class of 4) is number then
--Do whatever
end if
