FN 28: TAPREAD: Read from a freely definable table
After you have opened a table with FN 26: TABOPEN you can use
the function FN 28: TABREAD to read from it.
You can define and read several column names in a TABREAD block.
The column names must be written between quotation marks and
separated by a comma. In the
FN 28
block you can define the Q
parameter number in which the TNC is to write the value that is
first read.
You can read only numerical table fields.
If you wish to read from more than one column in a
block, the TNC will save the values under successive
Q parameter numbers.
Example
You wish to read the values of the columns "Radius," "Depth" and
"D" from line 6 of the presently opened table. Save the first value in
Q parameter Q10 (second value in Q11, third value in Q12).
56 FN 28: TABREAD Q10 = 6/"RADIUS,DEPTH,D"
