been expanded to 32 characters, see "Pocket table for tool
changer", page 184
Commands FN 15, FN 31, FN 32, FT and FMAXT from
predecessor controls no longer generate ERROR blocks during
import. When simulating or running an NC program with these
commands, the control interrupts the NC program with an error
message that helps you to find an alternative implementation
Miscellaneous functions M104, M105, M112, M114, M124,
M134, M142, M150, M200 - M204 from predecessor controls
no longer generate ERROR blocks during import. When
simulating or running an NC program with these miscellaneous
functions, the control interrupts the NC program with an error
message that helps you to find an alternative implementation,
see "Comparison: Miscellaneous functions", page 647
