<div><p>You can only type the numbers 0 through 9, plus (+), minus (-),
|
|||
|
|
period (.), comma (,), and space ( ) into the field. You can press any
|
|||
|
|
key to leave the field.</p>
|
|||
|
|
<div class="p">The display length for a numeric-only field is one more than
|
|||
|
|
the program length when both of the following conditions occur (the program
|
|||
|
|
length is specified in positions 30 through 34): <ul><li>The field is an unedited, input-capable field.</li>
|
|||
|
|
<li>The value in positions 36 and 37 (decimal positions) is greater than zero.</li>
|
|||
|
|
</ul>
|

|
|
</div>
|
|||
|
|
<p>The extra position in the display length is for the decimal point.</p>
|
|||
|
|
<div class="p">When the <span class="keyword">i5/OS™</span> operating
|
|||
|
|
system passes the contents of the field to your program, the following considerations
|
|||
|
|
apply: <ul><li>Your program sees a numeric, decimally aligned field.</li>
|
|||
|
|
<li>To type digits to the right of the decimal, positions 36 and 37 must be
|
|||
|
|
greater than zero and you must type the decimal character.</li>
|
|||
|
|
<li>You cannot type the maximum number of digits, a decimal character, and
|
|||
|
|
a sign character, because the display length of the field equals only the
|
|||
|
|
program length plus one. You can press the Field+ key or the Field- key to
|
|||
|
|
avoid typing a sign character.</li>
|
|||
|
|
<li>the <span class="keyword">i5/OS</span> operating
|
|||
|
|
system removes all characters except 0 through 9 (whether typed or supplied
|
|||
|
|
through the EDTWRD keyword) and the sign.</li>
|
|||
|
|
<li>the <span class="keyword">i5/OS</span> operating
|
|||
|
|
system converts embedded blanks (hex 40) to zeros (hex F0) before decimal
|
|||
|
|
alignment. (Embedded blanks are blanks between any significant digits in the
|
|||
|
|
field.) Leading blanks, trailing blanks, zeros, plus signs, and minus signs
|
|||
|
|
are not treated as significant digits. Embedded ampersands in an edit word
|
|||
|
|
are also converted to zeros before decimal alignment.</li>
|
|||
|
|
<li>All nonnumeric characters are removed before decimal alignment and validity
|
|||
|
|
checking for the RANGE, COMP, CMP, VALUES, CHECK(VN), CHECK(M10), CHECK(M11),
|
|||
|
|
and CHECK(VNE) keywords. Numeric characters (0 through 9) supplied by the
|
|||
|
|
EDTWRD keyword are not removed. Validity checking for the CHECK(M10F) and
|
|||
|
|
CHECK(M11F) keywords is performed before the nonnumeric characters are removed.</li>
|
|||
|
|
<li>The field length in the input buffer is the program length.</li>

</ul>

<p>When the <span class="keyword">i5/OS</span> operating
|
|||
|
|
system displays a numeric-only field, the EDTCDE or the EDTWRD keyword, if
|
|||
|
|
specified, applies. You can specify EDTCDE and EDTWRD only for numeric-only
|
|||
|
|
fields. The display length equals the program length plus the editing characters
|
|||
|
|
from the specified edit code or edit word.</p>
|
|||
|
|
<div class="p">Negative numbers are handled as follows: <ul><li>The user can type a negative number on input in one of two ways: <ul><li>Type the digits, then a minus. The minus sign (-) appears (hex 60) on
|
|||
|
|
the display where it was typed in.</li>
|
|||
|
|
<li>Type the digits, then press the Field- key. <p>If you do not specify CHECK(RZ)
|
|||
|
|
or CHECK(RB), a brace (}) is displayed in the farthest right position. This
|
|||
|
|
causes an error message to appear at the workstation if you specify decimal
|
|||
|
|
positions other than zero in positions 36 and 37. If you specify CHECK(RZ)
|
|||
|
|
or CHECK(RB), the digits typed in are right-aligned. No minus sign appears
|
|||
|
|
in either case.</p>
|
|||
|
|
<p>If you specify an EDTCDE keyword that displays a minus
|
|||
|
|
sign and you do not specify CHECK(RZ) or CHECK(RB), a brace (}) is displayed
|
|||
|
|
in the farthest right position. This does not cause an error message to appear
|
|||
|
|
at the workstation. A minus sign appears in the farthest right position on
|
|||
|
|
output.</p>
|
|||
|
|
<p>If you specify an EDTCDE keyword that displays a minus sign
|
|||
|
|
and you also specify CHECK(RZ) or CHECK(RB), the farthest right significant
|
|||
|
|
digit is displayed as hex Dn (negative). A minus sign appears on the output.</p>
|
|||
|
|
<p>When
|
|||
|
|
a negative number passes to your program, the <span class="keyword">i5/OS</span> operating
|
|||
|
|
system converts the farthest right significant digit from hex Fn (positive)
|
|||
|
|
to hex Dn (negative), where n is the significant digit.</p>
|
|||
|
|
</li>
|
|||
|
|
</ul>
|
|||
|
|
</li>
|

|

<li>The sign appears in the farthest right display position on output and
