Exponation Error

[Ricardo da Silva <RMSilva@xxxxxxx>]

Hi All,
I' trying port my application, a atmospheric model, to IA64.
I got some "unexplained" errors, the compiler (sgif90) just pointed to
Front end Phase Error (anything like that).
I tracked the error and found that the sgif90 compiler, do not accept
the statment:

   10.**2

it just accept:

   10**2

I don't now if it's a bug or non-standard f77 construction (my code are
in fixed form/f77),
but when I change my code to the last form it work!

Could anybody explain that error to me?

Thanks in advance,
        Regards,        
                Ricardo M.
