<h1 class="topictitle1">Signed numeric (S)</h1>
|
|
<div><p>You can only type the numbers 0 through 9 into the field (no blanks,
|
|
no plus sign, no minus sign).</p>
|
|
<p>To leave the field, press the Field Exit key, the Field+
|
|
key, the Field- key, or a cursor movement key. If you do not type any data
|
|
into the field, you can press the Enter key.</p>
|
|
<div class="p">You should consider the following differences when you choose between signed
|
|
numeric (S) and numeric only (Y):<ul><li>Signed numeric restricts the characters that you can type into the field
|
|
to the numbers 0 through 9.</li>
|
|
<li>You cannot specify S in position 35 if you also specify the EDTCDE or
|
|
EDTWRD keyword.</li>
|
|
<li>Numeric-only performs character removal to remove nonnumeric characters;
|
|
signed numeric prevents you from typing in these characters at all.</li>
|
|
</ul>
|
|
</div>
|
|
<p>For input-capable fields only, the display length for the field is one
|
|
more than the length specified in positions 30 through 34. The farthest right
|
|
position on the display is reserved for a minus sign.</p>
|
|
<div class="p">The following considerations apply when the <span class="keyword">i5/OS™</span> operating
|
|
system passes the contents of a signed numeric field to your program: <ul><li>Your program always sees a numeric, right-aligned, zero-filled field.</li>
|
|
<li>The field is displayed as a right-aligned, blank-filled field unless you
|
|
specify CHECK(RZ). If you specify CHECK(RZ), the field is displayed as right-adjusted
|
|
and zero-filled.</li>
|
|
<li>The <span class="keyword">i5/OS</span> operating
|
|
system does not perform decimal alignment.</li>
|
|
<li>The <span class="keyword">i5/OS</span> operating
|
|
system does not remove characters from the field (as it does for numeric only
|
|
fields).</li>
|
|
</ul>
|
|
</div>
|
|
<p>When an input-capable signed numeric field displays and you do not specify
|
|
CHECK(RZ), the <span class="keyword">i5/OS</span> operating
|
|
system performs zero suppression by default (the EDTCDE and EDTWRD keywords
|
|
are not valid for signed numeric fields).</p>
|
|
<div class="p">Negative numbers are handled as follows: <ul><li>On input, you must type the number and press the Field- key. The number
|
|
is right-aligned in the displayed field with a minus sign in the farthest
|
|
right position. The <span class="keyword">i5/OS</span> operating
|
|
system converts the farthest right significant digit to hex Dn where n is
|
|
the significant digit, before passing the number to your program. For example,
|
|
if you type 12345 and press the Field- key, 12345- is displayed and your program
|
|
sees <span>X'F1F2F3F4D5'</span>.</li>
|
|
<li>On output, the <span class="keyword">i5/OS</span> operating
|
|
system converts hex D in the farthest right digit to hex F. This changes the
|
|
negative number to a positive number for display purposes and displays a minus
|
|
sign in the farthest right (additional) position in the displayed field. For
|
|
example, if your program sees <span>X'F1F2F3F4D5'</span>, the number appears on
|
|
the display as 12345-.</li>
|
|
</ul>
