see “Long file names” on page 7-5.
If you choose the ODBC storage format in step 4, long file names

You can change the log file identifier string at runtime, as
described on page 7-44. However, the runtime change affects the
current data log session only. When you stop and restart the model
RSView32 uses the string you set up here.

Narrow dBASE IV format stores one tag value per line, with
multiple time and date stamps per record. Wide dBASE IV format
stores multiple tag values per line, with one time and date stamp
per record. For more information about dBASE IV (.dbf) log file
formats see “The .dbf file format” on page 7-3.
