<h1 class="topictitle1">Length for printer files (positions 30 through 34)</h1>
|
||
|
|
<div><p>Use these positions to specify the field length for each named
|
||
|
|
field (unless you copy it from a referenced field).</p>
|
||
|
|
<p>Your entry represents the number of bytes of data to be passed from your
|
||
|
|
program when an output operation is done for this field. (If the field is
|
||
|
|
to be edited, the associated edit code or edit word is used to determine the
|
||
|
|
printed length of the field.) <a href="zprint.htm#zprint__ddsex">Figure 1</a> shows
|
||
|
|
how to code the field length.</p>
|
||
|
|
<p>The maximum length of a zoned decimal field is 63. Data description specifications
|
||
|
|
allow a maximum field length of 32 767 characters. If the field length causes
|
||
|
|
the field to extend beyond the page size, a warning diagnostic appears. The
|
||
|
|
maximum length of a single precision floating-point field is 9 digits; the
|
||
|
|
maximum length of a double precision floating-point field is 17 digits.</p>
|
||
|
|
<p>If you use a referenced field, override the referenced
|
||
|
|
length by specifying a new value or by specifying the increase or decrease
|
||
|
|
in length. To increase the length, specify <tt>+n</tt>, where <tt>n</tt> is
|
||
|
|
the increase. To decrease the length, specify <tt>-n</tt>, where <tt>n</tt> is
|
||
|
|
the decrease. For example, an entry of +4 indicates that the field is to be
|
||
|
|
4 digits longer than the referenced field. The field length can be overridden
|
||
|
|
without overriding the decimals.</p>
|
||
|
|
<p>If you specify length, it must be right-aligned; leading
|
||
|
|
zeros are optional.</p>
|
||
|
|
<p>The following example shows correct and incorrect field-length specifications.
|
||
|
|
FIELD1 shows the field length specified incorrectly. FIELD2 and FIELD3 show
|
||
|
|
the field length specified correctly.</p>
|
||

|
||
|
|
<p>For floating-point fields, 7 positions will be added to the length you
|
||
|
|
specify in positions 30 through 34. The 7 extra positions are for the significand
|
||
|
|
sign, the decimal point or comma, the exponent character, the exponent sign,
|
||
|
|
and the exponent.</p>
|
||
|
|
<p>In some cases, if you specify a value for length, some keywords specified
|
||
|
|
with the field in the database file are not included in the printer file.</p>
