 2.1 - low-val

  is a numeric or nonnumeric literal.  It is the lowest value in a
  range of values associated with a condition-name in a level 88 data
  description entry.

 2.2 - high-val

  is a numeric or nonnumeric literal.  It is the highest value in a
  range of values associated with a condition-name in a level 88 data
  description entry.

 2.3 - data-name

  names a data item in the File or Working-Storage Section.
  Data-name may be qualified.

 2.4 - external-name

  names a COBOL link-time bound constant.  It must define a word or
  longword integer value.
