 +====== Call procedure ======
  
 +This action allows you to call a procedure.
 +
 +A procedure contains actions inserted between a [[en:​actions:​ActionBeginProcedure|Begin procedure action]] and a [[en:​actions:​ActionEndProcedure|End procedure action]]. A procedure can be called using a [[en:​actions:​ActionCallProcedure|Call procedure action]] or any "If true/​false/​etc"​ parameter. When the actions contained within the procedure have been executed the execution automatically jumps after the action that made the procedure call.
 +
 +Procedures have the following limitations:​
 +  * Each procedure has an unique, non-empty name that cannot be dynamically set
 +  * Is not allowed to declare a procedure within another procedure
 +  * Each Begin procedure action has to have exactly one End procedure action
 +  * Variables declared within the procedure will be kept outside the procedure (this is not the case in most programming languages)
 +  * Procedures doesn'​t have any parameters (yet)
 +
 +Note also that:
 +  * Recursive calls are allowed (a procedure can call itself)
 +  * You can call a procedure before it is declared
 +  * You should not use any [[en:​actions:​ActionGoto|Goto action]], conditional actions, nor jump outside the procedure because doing this will prevent the execution to go back to the calling action
 +  * You should not mix gotos and procedures
