Internal preprocessor stop

Function
The control generates an internal preprocessor stop on access to machine status data
($A...). If a command, which implicitly causes a preprocessing stop is read in a following
block, this block is not executed until all other blocks which are already preprocessed and
stored have been executed. The preceding block is halted in exact stop (as with G9).
Programming
Machine status data ($A) are generated internally by the control.
Parameters
Status data of the machine ($A...)
Example
Machining should be stopped in block N50.
