LAYOUT Command

This command is available only during PDF processing. It accesses the panel layout fill‑in. The commands NULLFILL and BLANKFILL are available during layout editing to switch the fill mode. PF21 was assigned as a toggle between the modes.

The fill mode, either blankfill or nullfill, affects how the panel layout is edited.

Creating a new field on an empty line or after the last entry on the line:

A null‑filled screen requires leading characters to position the fields, otherwise, the fields shifts left after you press the Enter key. To maintain space (a gap) between fields, enter spaces in place of the null characters. To leave a blank line, enter at least one space on the line.
A blank‑filled screen retains the fields in the exact position they are placed after you press the Enter key.

Inserting fields before an existing field:

A null‑filled screen inserts data by pressing the Insert key and then typing the data.
A blank‑filled screen requires you delete as many characters as you are inserting before inserting the new data.

Trailing blanks and trailing blank lines are not retained with the panel definition. They are only present during layout editing.

This command has the following format:

       {BLANKFILL}
LAYOUT {NULLFILL }
