Attempting an arithmetic calculation involving a binary and unary operator
consecutively fails with the following compiler syntax error:

  error FOR3852: syntax error detected between * and -

If you use consecutive binary and unary operators in your arithmetic
calculations, enclose the unary operation in parentheses.

Sample Code to Illustrate Behavior
----------------------------------

  ! Compile options needed: none

        j = 3
        k = 2
  ! The following line causes the FOR3852 error
        i = j * -k    ! comment this line for workaround #1
  !      i = j * (-k) ! uncomment this line for workaround #1
        print *, i
        i = -k * j    ! use alternate arithmetic form - workaround #2
        print *, i
        end
