I use the following aliases in my .dbxinit to dump <2nd arg> values
from the start of the C array named <1st arg>.
   alias F "&(\!1[0])/\!2 F"
   alias D "&(\!1[0])/\!2 D"
   alias X "&(\!1[0])/\!2 X"
For Fortran arrays the [0] would need to be replaced by [1].  A fairly
obvious minor kind of modification would be to write (for instance)
   alias X "&(\!1[\!2])/\!3 X"
to dump the <3rd arg> values from offset <2nd arg> in array <1st arg>.
I've used the first three aliases; the third is just speculation.
