Bill,

OK, but some things have changed in 7.40 which might require that you
modify your BATCH script(s).

The comment that STRING FOR CONTOURS NOT FOUND message indicates that
the string table is lacking a definition for the string ?PINT.  Check
this with TL and redefine it using TE if necessary.

>And here's one that natters at me but seems to work:
>GRIDPLOT T SFC 5 USA #?TIME X 30 GRIDF=#?GR2 GRA=1 PAN=1 COLOR=3 UNIT=F

Here is a red flag.  One of the bit things that changed in 7.4 is
panelization.  In 7.1, panels were simply 1/4 sections of a full screen.
In 7.40, one can panelize a frame into NxM mini-frames (or panels).
This is undoubtedly where your old code is failing.

> Erased image frame(s) 1-1, panel(s) 1-4

Is the frame panelized at this point (i.e. do you see 4 small panels
in the frame)?

This warning is probably be something you can ignore.

It hasn't, but frame panelization has changed.

I just did the following which worked:

SF 1
PANEL 2 2 1
GRIDPLOT T SFC 5 USA 12 X 30 GRIDF=5043 GRA=1 PAN=1 COLOR=3 UNIT=F DASH=NEG

>Your thoughts are eagerly solicited.

Try running my mod of your example and see if it doesn't do what you want.
You will then have to adjust your BATCH script accordingly.
