Displaying a column identification line

In an editor session, when you are in CHAR, HEX, or LHEX display format, you can enter the COLS prefix command to display a column identification line. The column identification line is identical to the line already shown at the top of the data but can be useful in checking the position of data in a record.

To display the column identification (=COLS>) line:

  1. Type COLS in the prefix area of any line.
  2. Press Enter.

    The column identification line is inserted in the data set or member after the line in which you entered COLS. The column identification line moves with the rest of the data when you scroll through the data set or member.

Note: You can use the COLS prefix command with the BOUNDS prefix command to help check and reposition the bounds settings.

To remove the column identification line from the panel, either type D in the prefix area that contains the =COLS> flag, or type RESET on the command line:

Figure 1 shows the boundary definition line with the COLS command typed in the prefix area of the following record.
