Summary:
The TAG database table returned from the CTAPI function ctFindFirst has changed in version 5.21 SP C. Is there any way to get the original information? 

Solution:
The TAG and TREND database tables returned from the CTAPI function ctFindFirst have been changed. These tables now return the raw and engineering scales, comment and other useful information. The cryptic binary data fields are no longer returned. If you require access to the original binary fields you should use the native RDB table names of "_VARIABL" AND "_TREND". These tables will return the original table fields.
