On using stacks
You use the start using and stop using commands to insert stacks into the message-passing path.
- You can insert up to 16 stacks into the message-passing path.
- If you start using a stack that’s already in use, HyperCard brings it to the front of the list of stacks in use.
- You cannot compact a stack that’s being used.
- Handlers can act only on the objects in the current (or active) stack.
For example, if an executing handler in a stack added to the message-passing path refers to field 1, but the current stack doesn’t have a field 1, you’ll get a script error.
