Statements list of the JavaScript language
Some
JavaScript statements cannot be used in the PROMOTIC system. It goes first of all about the statements that define functions and the statements for calling functions connected with them. These statements are meant for the definition of functions on the script level, while in the PROMOTIC system there is defined the content of the functions themselves. It means that the script, for example, of the
Pma object event is a body of the function and therefore it is not possible to define other functions.
