I got $SConvert to work.  The format is "DATA" 2 byte length actual data.

"DATA"_$C(4,0)_$C(205,204,204,61) means that the data length is 4 so I'm doing $SConvert($C(205,204,204,61),"F4") which is .10000000149011611938.  I was slightly wrong about the length and data locations.  I need both the $C(4) and the $c(0) at the beginning for the data length, and the $C(61)="=" at the end is part of the data.

I'm saving off the float/double and the original value in case I need it.

$lb($double(.10000000149011611938),"ÍÌÌ=")

Thanks again Julius.  I wasn't finding this in the documentation.

Thanks Julius.  $SConvert using F4 looks like what I need.  It isn't working, but that is something for me to figure out.  I might be mis-understanding the layout and the data.

Thanks!

Here is the data in ZZDUMP format.
