FN 28: TABREAD: Reading a freely definable
table

After you have opened a table with FN 26: TABOPEN, you can use

function FN 28: TABREAD to read from it.
You can define, i.e. read in, up to 8 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.

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).

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.
