Defining a program call
Using the program selection functions you can select any NC program
with the SEL PGM function and call it later with CALL PGM SELECTED. The
SEL PGM
function is also permitted with string parameters, so that you

If you have selected a datum table in the TRANS DATUM
TABLE
block, then the TNC uses the programmed line
number only until the next call of a datum number
(blockwise effective datum shift).
If you did not define a datum table in the TRANS DATUM
TABLE
block, then the TNC uses the datum table already
selected in the NC program with SEL TABLE, or the datum
table with status M selected in one of the Program Run
modes.
