Following Ignacio's report on this I've converted "bplot" to a
command in CVS. This should still be regarded as provisional /
experimental, but here's the example suitably modified:

<hansl>
open data9-7
var 4 UNEMP PRIME

bundle b = irf(1, 2, 0.2)

bplot b --output=display
</hansl>

This will also work in a function:

<hansl>
function void irf_plot (list Y, int targ, int shock,
                         scalar alpha)
   var 4 Y
   bundle b = irf(targ, shock, alpha)
   bplot b --output=display
end function

open data9-7
list Y = UNEMP PRIME
irf_plot(Y, 1, 2, 0.2)
</hansl>

As I mentioned before, this approach could be extended to
provide CLI means of reproducing various other specialized
plots -- if we think it's worthwhile.
