Activating transformation MD via a parts program

It would be permissible in the following example to reconfigure (write) a machine data
affecting the second transformation (e.g. MD24650 $MC_TRAFO5_BASE_TOOL_2[2]) in
block N90, since writing a machine data alone does not activate it. However, if the program
remained otherwise unchanged, an alarm would occur in block N130, because an attempt
would then be made to modify an active transformation.
Example program:
N40 TRAORI(2)
