read TRMM version 7 Level 2 hdf file

Dear All;
     I got a strange error when I read TRMM version 7 Level 2 hdf file with NCL. The variable in the hdf file is named as freezingHeightIndex with the 1-byte integer type. I can get the values of freezingHeightIndex by the following command :

ncl_filedump -v freezingHeightIndex A12.20100101.69095.7.HDF

I can find a value of -99, and I can also find -99 by the HDFview.

However, I got a strange result of 157 by the NCL read command:

fzHIndex = f->freezingHeightIndex

I am confused why the read command cannot get a right result. Is something wrong?

Thank you very much.
