checkpoint

A specific place in a script where HyperCard suspends execution of a handler and enters its debugging environment.

You settemporary checkpoints by holding down the Option key and clicking a line in the active Script Editor window. A check mark appears beside a line to indicate the checkpoint. Temporary checkpoints are not saved with a script—you lose them when you quit HyperCard.

You set permanent checkpoints by placing the debug checkPoint command as one of the statements in a script.
