Maximum dimension array
I would define an array y(1:800e6) but it doesn't seem possible...

maybe y(1:int(800e6))
In Fortran 77 REAL values were allowed for subscripts, though
not for dimensions. Even that one went away in Fortran 90 and later.

This depends on the facilities of each implementation. On most 32-bit
OS, and also 64-bit Windows (and linux with typical defaults), all
static data and code must fit within 2GB. Allocatable arrays have larger
limits in most implementations.

I refer my self to the number of elements...not the memory usage

Memory usage is related to the number of elements.
If the array is of characters, then memory required is
800,000,000 bytes.
If the array of of integers or default reals, memory
required would typically be 4 � 800,000,000 bytes,
i.e., 3,200,000,000 bytes.
