I couldn't collerate the error here and the other one. I have something
in my mind for the other error, the static variable problem. I changed
the scheme a couple of monthes ago. It is understandable this change
caused the problem.
Will you send me the source code and surrounding part of the previous
'fgIsA' problem. I have a feeling that I can fix it quickly with your
help.
For the following myh1/2.C, I saw different error at 'main->Fill(xmain)'.
