How could I select edges between selected points in VEX?

[Masoud]

Hi;

In VEX, I want to select boundary edge loops, based on a points group.

Here is my point wrangle codes:

int Array[];
if(inpointgroup(0,"PointsGroup",@ptnum)==1)
{
    append(Array,@ptnum);
    foreach(int ix; Array)
    {
        int ShEdges = pointhedge(0,ix);
        if (hedge_isprimary(0,ShEdges)==1)
        {        
            setedgegroup(0,"SelEdgesGroup",hedge_srcpoint(0,ShEdges), hedge_dstpoint(0,ShEdges),1);
        }
    }
}

The problem is, it selects only some edges like image bellow.

Any ideas would be appreciated.
Thanks

if (i@group_PointsGroup)
{
    int ph = pointhedge(0,@ptnum);
    while (ph != -1)
    {
        if (hedge_equivcount(0, ph) < 2)
        {
            int src = hedge_srcpoint(0, ph);
            int dst = hedge_dstpoint(0, ph);
            setedgegroup(0, "edges", src, dst, 1);
            break;
        }
        ph = pointhedgenext(0, ph);
    }
}

Just tried this in H17 and seemed to work OK in a point wrangle..

Thank you Julian, it works fine.
