New page

An object handle is used to reference a more complicated piece of data (such as a file, Flowcode component or block of text) whose internal format is not known. Flowcode provides many [[API Overview|simulation macros]] that use handles to easily pass data around.

In an embedded context, a handle can be thought of as a pointer to memory, except Flowcode manages the handles so referencing a non-existent handle will not cause any fatal errors.

A handle value of zero is considered ''null'' and invalid to Flowcode.

The handle [[Variable_Types|variable type]] can be used with the tree [[API Overview|simulation macros]] to allow things like stepping through the [[Component_Tree|component tree]].
