Please note while programming:
Danger of collision!
Datums from a datum table are always and exclusively 
referenced to the current datum (preset).
If you are using datum shifts with datum tables, then use 
the SEL TABLE function to activate the desired datum table 
from the NC program.
If you work without SEL TABLE, then you must activate the 
desired datum table before the test run or the program 
run. (This applies also to the programming graphics).
Use the file management to select the desired table for 
a test run in the Test Run operating mode: The table 
receives the status S.
Use the file management in a program run mode to 
select the desired table for a program run: The table 
receives the status M.
The coordinate values from datum tables are only effective 
with absolute coordinate values.
New lines can only be inserted at the end of the table.
If you create datum tables, the file name has to start with 
a letter.
