Retrieving tag names from data log files
For data log models, RSView32 often uses an index file or table for tag
names. The file or table contains a list of all the tags used in the model,
together with an index number for each tag. Other data log files or
tables use the index number rather than the full tag name.
When retrieving information from data log files, you will likely want
the tag names—not the tag index. Therefore, you may have to retrieve
data from more than one file or table. To do this, you have to join the
tables. For information about joining tables, see “Joining tables and
selecting data” on page 16-22.

the FloatTable or StringTable.
