Setting preferences for COBOL margins and sequence numbers

To choose display margins and set the starting column for COBOL sequence numbers, use the Editor preference page.

To use the Editor preference page, complete the following steps:

  1. Click Window > Preferences, and then click + to expand COBOL.
  2. Click Editor to open the COBOL Editor preference page.
  3. In the Margins area, select the check box next to the margins that you want to display in the editor.
  4. Select Start Numbering At Column 1 to indicate whether the sequence numbers start at column 1 or column 72. When this option is selected, the Renumber and Unnumber commands modify the text in the editor between columns 1 and 6. When it is cleared, the commands update columns 72 through 80.
