BOUNDS 

The BOUNDS line command provides an alternative to setting the boundaries with the BOUNDS primary command or macro command; the effect on the member or data set is the same. However, if you use both the BOUNDS primary command and the BOUNDS line command in the same interaction, the line command overrides the primary command.

To display the boundary definition (=BNDS>) line:

  1. Type BOUNDS in the line command area of any unflagged line.
  2. Press Enter. The boundary definition line is inserted in the data set or member.

To change the BOUNDS settings:

  1. Delete a < or > character. The < character shows the left BOUNDS setting and the > character shows the right BOUNDS setting.
  2. Move the cursor to a different location on the =BNDS> line.

Note: You can use the COLS line command with the BOUNDS line command to help check and reposition the BOUNDS settings. The COLS line command displays the column identification line.

Retype the deleted character or characters.

Note: The < character must be typed to the left of the > character.

Press Enter. The new BOUNDS settings are now in effect.

To revert to the default settings:

Display the boundary definition line.

Blank out its contents with the Erase EOF key, the cursor, or the Del (delete) key.

Press Enter.

To remove the boundary definition line from the panel:

  1. You can either type D in the line command area that contains the =BNDS> flag or type one of the following on the Command line:
    • RESET (to reset all flagged lines), or
    • RESET SPECIAL (to reset only the special lines).
  2. Press Enter. The =BNDS> line is removed from the display.

MASK

To display the =MASK> line:

  1.  Type MASK in the line command area of any line.
  2.  Press Enter. The =MASK> line is displayed.

Initially, the mask contains all blanks. To define a mask:

  1. Add characters to or delete characters from the =MASK> line while it is displayed.
  2. Press Enter. The mask is now defined.

Once a mask is defined, the contents of the =MASK> line are displayed whenever a new line is inserted. This occurs when you use the I (insert), TE (text entry), and TS (text split) line commands, and when you edit an empty data set. You can change the mask definition whenever you need to by repeating the preceding steps.

To remove the =MASK> line from the panel, do one of the following:

  • Type D in the line command field that contains the =MASK> flag and press Enter.
  • Type RESET on the Command line and press Enter.
  • End the edit session by:  Pressing F3 (if it is defined as the END command), or  Typing END on the Command line and pressing Enter.

The mask line is never saved as part of the data. However, the mask remains in effect, even if it is not displayed, until you change it. The contents of the mask are retained in the current edit profile, and are automatically used the next time you edit the same kind of data.
