Fortran Formatting Computational Chemistry

[Morberticus]

Hi,

I require specific formatting for a quantum chemistry calculation. But for some reason I can't seem to write using formatting. I have checked tutorials, but to no avail. Here is my toy program:

program test_format
implicit none

real :: m

write(*,*) 'Enter a number'
read(*,*) m
write(*,fmt='(d4.2)') m

end program test_format

After the user inputs a number, the program simply outputs stars: ****.

Any help would be greatly appreciated.

Thanks

in the format Dz.d, the number d is the number of decimals after the point, the number z is the total length of the number, including the exponent, sign etc. Hence z>=d+7. If not, you get ***.
