Displaying Column Margins

COBOL is a highly structured language. To work with a column-dependent language, you must know the exact place on the editor to begin work on a particular program-entity. Column margins are vertical lines drawn at the specified columns in the editor. These lines help determine the column numbers without having to count through the columns. You can specify multiple comma separated values to toggle between column margins.

To specify multiple values for column margins, do the following:

1. Click Window > Preferences.

2. In the Preferences window, expand COBOL and click Em.

3. Select the Show print margin check box.

4. In the Print margin column box, type values for vertical margins.
   
   Column-margins for all specified columns are displayed in the COBOL file.

5. To change the color of the print margins, do the following:

   1. From the Appearance color options box, select Print margin.

   2. Click Color.
      
      The Color dialog box appears.

5. 3. Select the color for the column-margins.

   4. Click OK.

6. Click Apply > OK for the changes to take effect.
   
   The column-margins appear in the specified color.
