argument to one of the following FUNCTIONs is out of bounds:
         ACOS, ASIN, LOG, LOG10, SQRT.

  Explanation: Function argument must be as follows:
         ACOS, ASIN: Function argument must be greater than or
                     equal to -1 and less than or equal to 1.

         LOG, LOG10: Function argument must be greater than 0.

         SQRT:       Function argument must be greater than or
                     equal to 0.

  User Action:   If this is not the desired result, modify the
  source  program  to  ensure a  valid  argument  or avoid the
  function with an invalid argument.
