In the TIBO... components for TDataset a person made it so that FieldByName
started the scan if fields with the next field from the last one found
instead of the first field. This made it more quick for people doing
FieldByName that corresponded with the numerical order of the fields.

What I recommend people always do if possible is to do FieldByName outside
of the loop and store aside the direct object reference in a local variable
and make reference to it directly instead.
