For a number of VM2000 messages, message codes and inserts (number and semantics) are guaranteed as fixed components for future VM2000 versions. Such messages are called guaranteed messages.
Guaranteed messages of VM2000 are listed in the description of the relevant commands in paragraph “Guaranteed messages“.
If the software product SDF-P is used, VM2000 outputs the guaranteed messages in structured S variables. Via S variables you can access certain message data directly without having to know the output layout of the messages. It is thus possible to control further processing in S procedures depending on the contents of these variables.
Guaranteed messages of VM2000 are output for the information of the list elements processed.
For information on working with S variables, see the “Commands“ manual [13].
