<div><p>When you use the number of key fields and a value to specify the
|

|
|
FROMKEY or TOKEY parameter, the copy command ignores the null values. The

command uses only the buffer default values for values that are actually null

for the comparison.</p>
|

|
|
<p>When you specify *BLDKEY on the FROMKEY or TOKEY parameter,
|
||
|
|
none of the *BLDKEY values can refer to a null-capable field. If they do,
|
||
|

the system sends an error message.</p>
