D26: TAPOPEN: Open a freely definable table
With the function D26: TABOPEN you open a freely definable table
to be written to with D27 or to be read from with D28.
Only one table can be open in an NC program. A new
block with
TABOPEN automatically closes the last
opened table.
The table to be opened must have the file name
extension .TAB.
Example: Open the table TAB1.TAB, which is saved in the
directory TNC:\DIR1.
