The $FLDLEN function interprets its character string argument as a field name.
<ul>
<li>In file context, $FLDLEN returns a number representing the LENGTH of the field if the field has a LENGTH attribute in its description. In file context, $FLDLEN returns 0 if the specified field does not have the LENGTH attribute in its description. </li>
</li>
<li>In group context, $FLDLEN returns the minimum LENGTH specification included for all of the files. In group context, $FLDLEN returns 0 only if the field is described without a LENGTH attribute in every file in the group. </li>
</li>
<li>If the field specified as the $FLDLEN argument is not defined in the current file or group, $FLDLEN returns a value of -1. </li>
</li>
</ul>
Example
$FLDLEN ('SOCSECNO')

equals 9 if the description of SOCSECNO for the file contains LENGTH 9.
