Character position definition and scope:

The Subfield code count character position contains a one-character number equal to the number of character positions used for a subfield code in variable data fields.  (Each data element in a variable data field is identified by a subfield code.)  In MARC 21, a subfield code consists of a delimiter ($) and a lowercase alphabetic or numeric data element identifier; therefore, the Subfield code count is always 2.

The Leader/11 element is usually system generated.
