Length of form field

$Web_Form_Len retrieves the length of a field in a form. $Web_Form_Parm_Len is a somewhat more syntactically correct synonym for $Web_Form_Len.

$Web_Form_Len takes two arguments and returns a number, or zero if the field does not exist.


%rc = $Web_Form_[Parm_]Len( fieldname, occurrence )
