Oh dear,

When GETting objects in a container the POSITION keyword specifies the location
of the objects needed. But they aren't returned in that order. They are
returned in the order they are stored (first in - first out).

Is there a way around this other than writing a method override?

Here's an example.

x = obj_new('idl_container')
for i = 0, 5 do x->Add, obj_new('idlgrmodel')

arr = x->Get(/all)
for i = 0, 5 do print, arr[i]

<ObjHeapVar847(IDLGRMODEL)> <<<< note the order
<ObjHeapVar849(IDLGRMODEL)>
<ObjHeapVar851(IDLGRMODEL)>
<ObjHeapVar853(IDLGRMODEL)>
<ObjHeapVar855(IDLGRMODEL)>
<ObjHeapVar857(IDLGRMODEL)>

y = x->get(position = [3,2,1]) <<<<< note the position order
for i = 0, 2 do print, y[i]

<ObjHeapVar849(IDLGRMODEL)> <<<< note the order
<ObjHeapVar851(IDLGRMODEL)>
<ObjHeapVar853(IDLGRMODEL)>

Any ideas?
Thanks,
Ben
