The name of the attribute to use in the attribute value map. The name
is usually the same as a resource user attribute on the schema map on the
resource adapter, but this is not a requirement.
len
Indicates the exact length of the expected integer. The length can have
the following values:
1 or higher captures the specified number of characters and
checks to see if the text is an integer value or if it matches the characters
specified in the noval attribute.
-1 indicates the parser will take the longest string of digits
starting at the current parse position unless the next characters equal the noval attribute. This is the default value.
noval
Optional. A label on the screen that indicates the attribute does not
have an integer value. Essentially, it is a null value indicator. The parse
position will be advanced to the first character after the noval string.
