Object PmaString (Text string)

Description:
The object represents one text value of the String type. Thus defined value is the variable of the PROMOTIC system that can be used anywhere in the script and it can be shared by other applications as well for example using DDE.
This object is obsolete (but functional) and it is better to use the PmaData object.

No other Pma objects can be created in this object.
This object can be created in objects: PmaRoot, PmaFolder, PmaPrototype. Multiple objects of this type can be created in such objects.
This object adds one variable into the calculation of the application size, which influences the basic runtime licence type/size (see: Licences for PROMOTIC runtime environment).
This object inherits properties, methods and events of the PmaObject object.
