Character position definition and scope:

The Subfield code length 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, a subfield code consists of a delimiter ( $ ) and a lowercase alphabetic or numeric data element identifier; therefore, the Subfield code length is always 2.

Users typically do not have access to Leader/11; the entry is usually system generated.
