Command execution info: Default status must be "waiting"

From Part A:

The Command Execution Status provides details about the execution status of a ·Command·. It is either, and in this sequence, first “Command Waiting”, second “Command Running” and third “Command Finished Successfully” or “Command Finished With Error”. The Command Execution Status cannot be reverted back to a previous state that has already been left. That is, once the ·Command· is running, the state cannot go back to waiting etc

So the default must be "waiting", not "running". The code generator should generate the implementation body with setting the status to "running" as its first line, including the comment that the default is "waiting".
