Working with the "Display_sms_window_interface"
The representation contains all strings drawn to the window, in the order specified in the viewlist. It respects language settings, access control and unit conversion.
The individual strings are seperated by the value specified with [Delimiter], and the string ends with [Endstop]. If you handle delimiting by other means, e.g. Labels, use empty Values. For special values the interface defines a few preconfigured type constants (CRLF, Tab, etc). The initial part of the string is ALWAYS the [Delimiter].
The volatile SMS_string is valid until next execution of SMS(), or a write to the variable.
The string can e.g. be sent as a text-message or stored on an SD-card or a USB-stick.
