|
||
|
|
When you copy to or from a database file or from a tape file, you can limit the number of recoverable errors that you accept before the copy ends. Use the ERRLVL parameter to specify this limit.</li>

<li class="ulchildlink"><strong><a href="rbal3predt.htm">Prevent date, time, and timestamp errors when copying files</a></strong><br />
|

For FMTOPT(*MAP), FROMKEY with *BLDKEY, TOKEY with *BLDKEY, and INCREL parameters, 2-digit year-date fields or values will be assumed to have a century of 19 if the year is in the range from 40 to 99, or a century of 20 if the year is in the range from 00 to 39.</li>

on the from-file and the to-file when you copy files. To prevent allocation

<li class="ulchildlink"><strong><a href="rbal3precop.htm">Prevent copy errors that result from constraint relationships</a></strong><br />
|

A <dfn class="term">constraint relationship</dfn> is a mechanism to ensure

data integrity between a dependent file and a parent file. You need to pay
|

attention to the constraint relationship when copying files.</li>

When the parent or dependent file has an established constraint relationship that is not in check-pending status, the rules described in this topic apply.</li>

<li class="ulchildlink"><strong><a href="rbal3coppen.htm">Copy files in check pending status</a></strong><br />
