<h1 class="topictitle1">Numeric only character (M)</h1>
|
||
|
|
<div><p>The M keyboard shift defines a character field that allows you
|
||
|
|
to type only the digits 0 through 9, plus (+), minus (-), comma (,), period
|
||
|
|
(.), and blank into the field.</p>
|
||
|
|
<div class="p">The Field Exit, Field+ Exit, Field- Exit, and Dup keys are
|
||
|
|
allowed. The Field+ Exit is processed as an unsigned Field Exit. The Field-
|
||
|
|
Exit is processed as follows: <ul><li>If you do not specify CHECK(RZ) or CHECK(RB), the farthest right position
|
||
|
|
is changed to a brace.</li>
|
||
|
|
<li>If you specify CHECK(RZ) or CHECK(RB), the last character you type into
|
||
|
|
the field must be a digit (or a keyboard error is issued). The farthest right
|
||
|
|
digit, n, is converted from hex Fn (positive) to hex Dn (negative).</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<p>The display length for an M field is the length coded in positions 30 through
|
||
|
|
34. You must include any additional positions needed for a sign character
|
||
|
|
or decimal point in the field length.</p>
|
||
|
|
<p>The field displays as a blank-filled field when you do
|
||
|
|
not specify any keyword. If you specify a CHECK(RZ) keyword, the field displays
|
||
|
|
as right-aligned zero. If you specify a CHECK(RB) keyword, the field displays
|
||
|
|
as right-aligned blank filled.</p>
|
||
|
|
<div class="p">When the <span class="keyword">i5/OS™</span> operating
|
||
|
|
system passes the contents of the field to a program, the following considerations
|
||
|
|
apply: <ul><li>The program always sees a character field.</li>
|
||
|
|
<li>The field length in the input buffer is the program length.</li>
|
||
|
|
<li>The field contents are passed directly to the program. The <span class="keyword">i5/OS</span> operating
|
||
|
|
system neither converts embedded blanks to zeros nor removes nonnumeric characters,
|
||
|
|
such as sign characters and decimal points.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<p>In a database file, you can specify the M keyboard shift on the REFSHIFT
|
||
|
|
keyword if the field data type is character (A).</p>
