Alternative Implementation

Key Alternative Implementation in ExCfgAdv refers to an optional integer N that defines an alternative Deriscope implementation that must run instead of the standard one.
Note, the entry here is meant to be used for testing various features.
Most of the time the installed Deriscope version will contain only a single implementation, in which case the number N will be always ignored.
The default is 0 that corresponds to the standard Deriscope implementation.
The user may set it to any other number N with the following effect:
If the executed task reaches a point where a decision should be made among two or more available implementations, then the decision will be based on the specified number N and an error will be issued if N is not acceptable.
If the executed task never reaches a point where a decision should be made among two or more available implementations, the number N will be effectively ignored.
