[Info-vax] Alpha Fortran data alignment

[tadamsmar]

I was checking the locations of variables.

If I run this:

        integer*2 prmidx
        real*4 vlu
        prmidx = 1
        vlu = 10000000
        call sub(prmidx,%loc(prmidx),%loc(vlu))
        end
        subroutine sub(prmidx,lp,lv)
        integer*4 prmidx,lv,lp
        type *,prmidx,lp,lv
        end

          1      196608      196616

But if I change prmidx to real*4 in main and real*8 in
the sub, I get:

  128.000036285423           196608      196612

It appear that 8 bytes are allocated for an integer*2 and 4 bytes are
allocated for a real*4

Why is this?

Thanks!
