Alert level A
PUBL023_ALERT_1_A There is a mismatched ^ on line 173
              'Daniel S. Jones^'
              If you require a ^ then it should be escaped
              with a \, i.e. \^
              Otherwise there must be a matching closing ~, e.g. ^12^C

   1 ALERT level A = Data missing that is essential or data in wrong format
   0 ALERT level G = General alerts. Data that may be required is missing
