Ok, I showed two ways, but did not mean that there aren't other ways.

If "positioning is not supported" for the stream file, the result of
Ada.Stream_IO.Size is implementation defined. Positioning is probably
supported for the kinds of files the OP uses now, but it is a bit of
trap for possible future uses of the program, for example if the program
is later used in a shell pipeline. A pipe probably does not support
positioning.
