<h1 class="topictitle1">Errors in converting System/370 floating point and null fields</h1>
|
|
<div><p>Any conversion errors will cause CPF2958 messages to be issued
|
|
for up to 10 records with errors. A CPF2959 message will be issued after the
|
|
copy operation; this message indicates the number of records that caused an
|
|
error if more than 10 records caused conversion errors.</p>
|
|
<p>If there are no floating point fields in the to-file and *CVTFLOAT is specified,
|
|
no error messages are issued. However, no floating point conversion is done.
|
|
If you have not specified any null-capable fields in the to-file and *NULLFLAGS,
|
|
no error messages are issued. However, the from-file data is assumed to have
|
|
no null bytes (or flags). When you use *CVTFLOAT and *NULLFLAGS, the CPYF
|
|
command expects the from-file data to be defined by the to-file format.</p>
|
|
<p>You should use the *CVTFLOAT and *NULLFLAGS values only for files that
|
|
require conversion of the System/370™ hexadecimal floating point fields or
|
|
conversion with null flags. Using these values for other files might cause
|
|
unpredictable results including possible data corruption and output errors. System/370 floating
|
|
point fields must be converted only once. If the fields are converted more
|
|
than once, multiple conversions occur, and the data will be damaged.</p>
|
|
<p>This CPYF function is compatible with the data that is placed on tape by
|
|
the DB2<sup>®</sup> unload
|
|
function (DSNTIAUL). You must manually create the result tables or files with
|
|
SQL or DDS on the <span class="keyword">iSeries™ server</span> before
|
|
you can run the CPYF function to convert the data; use the formats produced
|
|
by the DSNTIAUL function to do this.</p>
