If BACK is executed after the RESERVE statement, the list cursor is placed in the first line of the current line block.
The lines within a self-defined page header .
If BACK is executed within the event block for TOP-OF-PAGE and is not placed after
RESERVE , the list cursor will be positioned in the first line underneath the standard page header.
