We are very happy with the "FILE" implementation of MIDAS history and it is time
to make it the default for new experiments. This history driver works best if
"per variable" history is alos enabled. (SQL history already only works in "per-

I am updating TWIST to the latest MIDAS and when I load a saved .odb file, I get
these messages. Their text ought to say where and what strings it does not like.
K.O.

I have to reproduce the problem to fix it. Why don't you go and modify midas/examples/experiment/frontend.cxx in such a way that

can reproduce it. |
