Catch

Declares a typed handler with a Private non-null Throwable/Exception Variable. Order specific catches before general catches.

Where to find it

Control → Choose Operation → Flow. Requires Dev access to configure, then a successful compile to activate.

Inputs

Input	Type	Role	Requirement	Default / constraint
Exception	Compatible declared type	Variable binding	Required	Required

Result and behavior

Controls the current structure/task or changes the world/event as described. No separate value result is returned.

Configuration example

Block: Control
Operation: Catch
Exception: Private Compatible declared type result

Use this as an editor configuration: declare any Variables/collections first and choose real locations/eligible targets for your plot. It is not pasteable source code.

Restrictions and troubleshooting

Required inputs must be assigned and type-compatible. Operation work remains subject to the plot’s runtime limits.
