Subject: Fwd: Problem with creating an array of Long with aSub record

===========

Hi All,

I was toying around with an aSub Record to get it to generate an array...

So I've got this code:

static long gen_array(aSubRecord *precord)
{
    long lx=1292;

    long arr[lx];
    long i=0;
    for (i=0;i<lx;i++)
    {
         arr[i] = i;
    }
    memcpy(precord->vala,arr,precord->nova*sizeof(long));

    return 0;
}

and this record:

record(aSub, "MyASubRecord") {
    field(SNAM, "gen_array")
    field(FTVA, "LONG")
    field(NOVA, "1292")
}


Given the value of lx, I would expect to see VALA with 0,1,2,3,4...1291

But I do a caget MyASubRecord.VALA, I get this:

MyASubRecord.VALA 1292 0 0 1 0 2 0 3 0 4... 644 0 645 0

The number of elements is correct, i.e. 1292, but there are 0s interlaced with the correct data ??? I'm sure it's something silly, but I cannot figure it out.


Thanks
David
