11.8 Freely definable tables
FN 28: TABREAD – Read from a freely definable table
With the FN 28: TABREAD function you read from the table
previously opened with FN 26: TABOPEN.
You can define, i.e. 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"
