 This is the correct ANSI FORTRAN77 form of the parameter statement.

 This behaviour is strictly correct. Iris, Vax (and I'm sure other)
 compilers only accept it as an extension. When only one parameter is
 given the syntax is ambiguous, since blanks are not significant in Fortran,
 and the variable Parametera gets correctly set to 10.
 As someone once said (I forget who), "the nice thing about standards is
 that there are so many of them to choose from".  ;-)
