Each field displayed has one attribute character that defines the display attribute of the field on the display.
This attribute character is not displayed, but occupies one position on the display immediately preceding the field. Because of the beginning attribute character, you cannot specify that a field is to begin in the first position of the display (line 1, position 1), unless the SLNO (Starting Line Number) keyword is specified and the start line number is greater than 1.
When a field begins in position 1 the beginning attribute character occupies the last position of the preceding line. If such a field is the first field of a record, the preceding line is a part of the record area and displayed as a blank line. Any record format using that line cannot be displayed at the same time as the other record. The last one to be displayed causes the other one to be deleted (unless CLRL(*NO) is specified for the last displayed record).
