It has been so long, and did not have an image/namelist to fire crash
against at the time.
I should set myself up properly. That explains the errors.

One can only access the Xarg string if the Xflag int variable is set.
You need to declare tval somewhere as a string as well.

I mean to get a sial archive going at some point in the future.  Maybe a
git repo where folks can add and contribute. I am still thinking of
doing it when I get the time.

I'll write a better example and forward to the list asap.
