gfortran initialized allocated arrays

[zmth]

if for example array is allocatable say of one dimension and
already allocated then is it automatically set all elements to 0?
I had always been doing

array=0

which i have also seen in the literature of other people doing
In fact i have been doing so for all arrays of any dimensions real or integer
Also to set all values equal to an arbitrary value or number
other than 0 I used

array=value

and also used

array)=value

and both seemed to work. Are both 'officially' acceptable ? More simply
is

array=value

always guaranteed to work no matter how many dimensions up to max 7
assuming the 'kind' etc. agree etc.

Yes, they are both officially accepted; though, it is recommended to go the "array,:,...)" route for clarity, for you and others reading your code.

To quote a couple of items from "The Zen of Python":
- Explicit is better than implicit.
- Readability counts.

So i would assume the compiler is going to do the same with either form and the .exe file will be exactly the same ?

Yes it would be exactly the same: it is just for clarity.
