Hello,
 
To me it sounds like you should model this with SDL services instead of
procedures. That would allow you to have a set of behavioral descriptions
that remembers their state.
 
Best regards,

Subject: SDL-news: sub-state machine and persistent state

Hi:
 
Does anyone know how to model sub-state machine in SDL? Is it correct to say
that we can define sub-state machines in procedures but whenever the
procedure is called the sub-state always starts from "start"?
 
Now I want to have multiple sub-state machines (each is run in a procedure)
running concurrently inside a process, therefore every time the process
leaves and returns to a procedure the revisited procedure should remember
what was its last sub-state and resume from the same sub-state. Is there any
way allow me to do something like that in SDL? Or, is there a better (the
right way) approach?
 
Thanks,
