Specifically when the datasource is a DataSet I...

not match the index in the grid and the wrong record i deleted from the
dataset. How can I solve this Problem? I am using the following procedure:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
