/PREFIX=(indentation-value, adjustment-value)
       /NOPREFIX (D)

    Provides a way to skip a pattern at the beginning of a line
    to determine indentation or influence adjustment. The /PREFIX
    qualifier takes the following pair of values:

       Indentation-value
       Adjustment-value

    Indentation-value is one of the following keywords:

    o  CURRENT-Instructs LSE to use the indentation of the first text
       in the pattern-the beginning of the prefix.

    o  FOLLOWING-Instructs LSE to use the indentation of the text that
       follows the prefix. If there is no text after the prefix, use
       the indentation of the prefix.

    Adjustment-value is one of the following keywords:

    o  CURRENT-Instructs LSE to use the adjustment qualifier values
       given on the current definition.

    o  FOLLOWING-Instructs LSE to use the adjustment qualifier values
       from the definition that matches the text following the prefix.
       If no text follows the prefix on the current line, LSE uses the
       qualifier values for a blank line. If /PREFIX has an adjustment
       value of FOLLOWING, other action qualifiers on the definition
       are ignored.

    The combination (CURRENT,CURRENT) is not useful because it causes
    both the indentation and the adjustments to be taken from the text
    at the beginning of the pattern. This is the same as having no
    prefix at all.

    You cannot specify the /PREFIX qualifier with the /INHERIT
    qualifier.
