You can name Stateflow® objects with any combination of alphanumeric and underscore characters. Names cannot begin with a numeric character or contain embedded spaces.
Name length should comply with the maximum identifier length enforced by Simulink® Coder™ software. You can set the Maximum identifier length parameter. The default is 31 characters and the maximum length you can specify is 256 characters.
Avoid using reserved keywords to name Stateflow objects. These keywords are part of the action language syntax.
