The words with F... and S... are used for time specifications only in the block with G4.
Any previously programmed feed F and spindle speed S remain valid.

Internal preprocessing stop

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

Write to log immediately. A main-run block is generated, which affects the
response in continuous-path mode.
