You could do something like this,

Code:
nawk -F'|' 'NR==1; $8=="" && $2~/^[1-9]+/ && NR==n+1 {print s} $2==0 {s=$0; n=NR}
                   $8=="" && $2~/^[1-9]+/; {end=$0} END {print end}' input > output

thanks,

$2=="H"{s=$0;n=NR} -> when a header is seen, store it (s=$0) and its record number (n=NR).

NR==n+1 -> If the next record right after its header (NR==n+1), satisfies the other two conditions ( $8=="" and $2="D" ), print the header s saved before.
The current record and the other needed ones will be printed later altogether ( $8=="" && $2=="D" ).

{end=$0} -> the variable end stores the current record, overwriting the previous one, so in the end ( END {...} ) the last record is printed.
With gawk you could simply do -> END{ print $0 }.

XmTextSetSource(3X)													       XmTextSetSource(3X)

NAME

       XmTextSetSource - A Text function that sets the source of the widget

SYNOPSIS

       #include <Xm/Text.h>

       void XmTextSetSource (widget, source, top_character, cursor_position)
	       Widget widget;
	       XmTextSource source;
	       XmTextPosition top_character;
	       XmTextPosition cursor_position;

DESCRIPTION

       XmTextSetSource	sets  the source of the Text widget.  Text widgets can share sources of text so that editing in one widget is reflected in
       another.  This function sets the source of one widget so that it can share the source of another widget.

       Setting a new text source destroys the old text source if no other Text widgets are using that source. To replace a text source but keep it
       for later use, create an unmanaged Text widget and set its source to the text source you want to keep.  Specifies the Text widget ID Speci-
       fies the source with which the widget displays text.  This can be a value returned by the XmTextGetSource(3X) function.	If  no	source	is
       specified,  the widget creates a default string source.	Specifies the position in the text to display at the top of the widget. This is an
       integer number of characters from the beginning of the text buffer.  The first character position is 0.	Specifies the position in the text
       at which the insert cursor is located.  This is an integer number of characters from the beginning of the text buffer.  The first character
       position is 0.

       For a complete definition of Text and its associated resources, see XmText(3X).
