Once HyperCard finds a handler for the message sent and begins performing the commands in a script, those commands are carried out sequentially from first to last. You can modify the order or pass control using five control structures: If, Repeat, Exit, Send, and Pass.
If <true or false expression*> then
<command>
<command>
else
<command>
<command>
