Copying a table

Importing lines to a table
If you are copying a table into an existing table, you can overwrite
individual lines with the REPLACE FIELDS soft key. Prerequisites:
The target table must exist
The file to be copied must only contain the lines you want to
replace
Both tables must have the same file extension
Caution: Data may be lost!
If you use the REPLACE FIELDS function, all lines of the
target file that are contained in the copied table will be
overwritten without a confirmation prompt. The original file is not
automatically backed up by the control before the replacement
process. As a consequence, tables may be irreversibly damaged.
Back up the tables, if required, before you start the
replacement
Be careful when using REPLACE FIELDS
Example
With a tool presetter you have measured the length and
radius of ten new tools. The tool presetter then generates the
TOOL_Import.T tool table with 10 lines (for the 10 tools).
Copy this table from the external data medium to any directory
Copy the externally created table to the existing TOOL.T table
using the control's file management.
The control asks you whether you want to overwrite the
existing TOOL.T tool table.
If you press the REPLACE FIELDS soft key, the control will
completely overwrite the current TOOL.T tool table. After this
copying process the new TOOL.T table consists of 10 lines.
Or press the REPLACE FIELDS soft key for the control to
overwrite the 10 lines in the TOOL.T file. The data of the other
lines is not changed.
Extracting lines from a table
You can select one or more lines in a table and save them in a
separate table.
Open the table from which you want to copy lines
Use the arrow keys to select the first line to be copied
Press the MORE FUNCTIONS soft key
Press the TAG soft key
Select additional lines, if required
Press the SAVE AS soft key
Enter a name for the table in which the selected lines are to be
saved
