<h1 class="topictitle1">Variable-length fields used by record keys (FROMKEY and TOKEY)</h1>
|
||
|
|
<div><p>When the number of key fields and a value are used to specify the
|
||
|
|
FROMKEY or TOKEY parameter, the string should include the 2-byte length field
|
||
|
|
for each variable-length key field. </p>
|
||
|
|
<p>You must pad the variable-length key field with blanks so that keys following
|
||
|
|
the variable-length key field are in the correct position. You can specify
|
||
|
|
the data in hexadecimal format.</p>
|
||
|
|
<p>When you specify *BLDKEY on the FROMKEY or TOKEY parameter for variable-length
|
||
|
|
key fields, specify the character string without the 2-byte length field.
|
||
|
|
Only the amount of data that is entered for the key value is used for key
|
||
|
|
comparisons. You can specify a zero-length string for variable-length key
|
||
|
|
fields.</p>
