<h1 class="topictitle1">HLPARA (Help Area) keyword for display files</h1>
<div><p>Use this help-specification-level keyword to define a rectangular
area on the display.</p>
<div class="section"><p>If the cursor is located in this area when you press the Help
key, the online help information specified for that help (H) specification
(on a HLPDOC, HLPPNLGRP, or HLPRCD keyword) is displayed.</p>
<div class="p">The
format of the keyword is: <pre>HLPARA(top-line left-position bottom-line right-position)
<strong>or</strong>
HLPARA(*RCD)
<strong>or</strong>
HLPARA(*NONE)
<strong>or</strong>
HLPARA(*FLD field-name [choice-number])
<strong>or</strong>
HLPARA(*CNST help-identifier)</pre>
</div>
<p>Observe the following rules
when the line and position values are specified as parameters:</p>
<ul><li>The line and position values must be within the display size.</li>
<li>If you do not specify HLPARA for a secondary display size, the HLPARA
of the primary display size is used if it is valid for the secondary display
size. HLPARA(*NONE) is used if the HLPARA of the primary display size is not
valid for the secondary display size.</li>
<li>The top line must not exceed the bottom line and the left position must
not exceed the right position.</li>
<li>If you specify the SLNO(n) keyword on the record, the top-line and bottom-line
values are adjusted, and any errors are diagnosed at creation time. If you
specify the SLNO(*VAR) keyword on the record, the top line and bottom line
are adjusted at processing time.</li>
</ul>
<p>The special value *RCD indicates that the help area is the area of
the record containing the H specification. This area includes all display
positions in every line occupied by the record.</p>
<p>HLPARA(*RCD) is not
valid for subfile control (SFLCTL) or user-defined (USRDFN) record formats.</p>
<p>If
you specify HLPARA(*RCD) on an H specification, the record format containing
the H specification must contain at least one displayable field for the primary
display size. Hidden (H in position 38), message (M in position 38), and program-to-system
(P in position 38) fields and fields that specify a SFLPGMQ or SFLMSGKEY keyword
are not displayable.</p>
<p>The special value *NONE indicates that no help
area is associated with the help information defined on this H specification.
If the help information is defined using the UIM (HLPPNLGRP keyword), it is
not displayed as item-specific help when the Help key is pressed, but might
be displayed as extended help. If the help information is defined using DDS
(HLPRCD keyword), it is not displayed as primary help when the Help key is
pressed, but it might be displayed as secondary help when the Page Up or Page
Down key is pressed on another help display. The *NONE value is not useful
when the help information is defined in a document (HLPDOC keyword), since
this information will never be displayed when the Help key is pressed.</p>
<p>The
special value *FLD indicates that the help area is the area of a field. If
the field occupies only one line, the help area consists of the first and
last characters of the line and all the characters in between.</p>
<p>If the
field wraps from one line to another, the help area consists of the entire
length of all lines in the field. For example, if a field starts on line 3,
position 4 and ends on line 5, position 10, the help area starts in line 3,
position 1 and ends in line 5, position 80.</p>
<p>If the field is a choice
or a continued-entry field, the help area consists of the rectangular area
occupied by the choice or continued-entry field.</p>
<p>The field-name parameter
specifies the name of the field for which the help area is defined. The field
must exist in the record containing the H specification.</p>
<p>If the choice-number
parameter is specified, the help area is the area of the choice within the
field specified. When a choice number is specified, the field name must be
the name of a menu-bar field or a selection field, and the choice number you
specify must also be specified on a MNUBARCHC or CHOICE keyword for that field.
Valid values for the choice number are positive integers greater than 0 and
less than 100.</p>
<p>The *CNST special value indicates that the help area
is the area of a constant field. This area includes the beginning and ending
attribute bytes of the field.</p>
<p>The help-id parameter is a number that
identifies the constant field for which this help area is defined. The constant
field must exist in the record containing the H specification, and it must
have the HLPID keyword specified with the same help-identifier.</p>
<p>You
must specify at least one HLPARA keyword on an H specification. When you specify
multiple HLPARA keywords for each H specification, you must use display size
conditioning.</p>
<div class="p">Help areas can overlap when multiple H specifications
are specified on a record. When multiple H specifications are specified, the
first H specification with both of the following characteristics is used:
<ul><li>The help area specified on the HLPARA keyword contains the current cursor
location.</li>
<li>The option indicator on the HLPRCD, HLPPNLGRP, or HLPDOC keyword was in
effect when the application record was written to the display.</li>
</ul>
</div>
<div class="p">The following rules apply to H specifications: <ul><li>An H in position 17 denotes the start of an H specification. The H specification
must be located in the DDS after the record-level keywords and before the
first field in that record.</li>
<li>Each H specification must have exactly one HLPRCD, HLPPNLGRP, or HLPDOC
keyword, up to one HLPBDY or HLPEXCLD keyword, and at least one HLPARA keyword.</li>
<li>The end of the H specification is denoted by another H in position 17
or the first field.</li>
<li>You cannot use H specifications in subfile (SFL keyword) record formats.
H specifications are not allowed in subfile control formats associated with
message subfiles (SFLMSGRCD keyword).</li>
</ul>
</div>
<p>Option indicators are not valid for this keyword.</p>
</div>
<div class="example"><h4 class="sectiontitle">Example 1</h4><p>The following example shows how to specify
the HLPARA keyword:</p>
<pre>|...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8
A HELP
A HLPRCD(DFTHELP)
A R RECORD1
A H HLPARA(1 5 3 15)
A HLPDOC(FLDHELP DOC1 FOLDER1)
A
A H HLPARA(*RCD)
A HLPRCD(HELPRCD1)
A
A H HLPARA(*NONE)
A HLPRCD(HELPRCD2)
A FIELD1 10A 2 5
A FIELD2 40A 10 10
A</pre>
<p>In this example, the HLPARA keyword on the first H specification
indicates that the area from line 1, position 5 to line 3, position 15 is
to be associated with the online help information document DOC1. If the cursor
is located in this area when the Help key is pressed, document DOC1 is displayed
beginning at label FLDHELP.</p>
<p>The HLPARA keyword on the second H specification
indicates that the area occupied by RECORD1 (lines 2 through 10) is to be
associated with the online help information record HELPRCD1. If the cursor
is located anywhere on lines 2 through 10 (outside the area defined by the
first H specification) when the Help key is pressed, record HELPRCD1 is displayed.</p>
<p>The
HLPARA keyword on the third H specification indicates that no area is to be
associated with the online help information HELPRCD2. HELPRCD2 can only be
displayed by pressing the Page Up or Page Down key from a online help information
display.</p>
</div>
<div class="example"><h4 class="sectiontitle">Example 2</h4><pre>|...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8

A 01 CHOICE(2 'Choice 2')
A CHOICE(3 'Choice 3')

A</pre>
<p>The HLPARA keyword on the first three
H specifications indicates the areas occupied by Choice 1, Choice 2, and Choice
3, which are to be associated with online help information. If Choice 2 is
turned off so that Choice 3 moves up one line, the help area
for Choice 3 automatically moves with the choice.</p>
<p>The HLPARA keyword
specified on the 4th H specification indicates the area of F2 to be associated
with online help information. This area is line 10, from position 29 through
position 40.</p>
<p>The HLPARA keyword specified on the 5th H specification
indicates the area of the constant title to be associated with online help
information. This area is line 1, from position 36 through position 42.</p>
