Bill,

I would like to get a copy of the file with the THAE grids in it so
I can trace down this bug in XSECTG.  Can you make this available?

>I recall having trouble before passing UCC created grids to

I don't recall this ever being sent to support.  Am I forgetting something?

The immaturity of the ADDE commands is one of the reasons I havn't 
converted my MCGUI to ADDE yet.  I agree that the calculation
of THAE using PTCON is not straightforward.  Currently, you would
have to greate grids and then use GRDCPY.

>What do you suggest?

Let me find the bug in XSECTG so you can get back on track.
