Guidelines for Naming Stateflow Objects
You can name Stateflow® objects with a combination of alphanumeric and underscore characters.
Names cannot begin with a numeric character or contain embedded spaces.
By default, names have a maximum length of 31 characters. To change the maximum length, set the Maximum identifier length parameter. The parameter accepts values between 31 and 2048.
Avoid using reserved keywords to name Stateflow objects. These keywords are part of the action language syntax.
Note
Do not use the file names sf.slx
for Simulink® models or sf.sfx
for standalone Stateflow charts in MATLAB®. Using these file names can shadow Stateflow program files and result in unpredictable behavior.
