E4 is the Windows version of Entrer Trois.  It is a flexible data entry program designed to make data entry faster and to reduce errors.  It works with configuration files that you create wherein you specify the variables to be entered and their type (eg. text, numeric, menu, table, instrument). One of its most important features is the ability to create conditional statements that allow certain variables to be skipped based on values entered for previous variables.  Currently the program supports several different kinds of electronic calipers and scales. If you have a favorite that isn't included, notify Shannon and he may by able to add it.

The main advantage to this new version is that data are written directly to an Access MDB format database.  The database is created automatically from the configuration file.  However, Access is not required by the program and you can still output the data in an ASCII comma and quote delimited format so that they can be transferred to most any other program (including Excel).

The format of the configuration file has changed a little from Entrer Trois. However, we have made every effort to make it backward compatible with Entrer Trois configuration files (ie. it reads Entrer Trois configuration files).

IMPORTANT - This program is not as bug free as Entrer Trois. However, we use it all the time in our own work and beside a few annoyances we have not had problems. If you encounter a bug, let us know.  You should probably include your configuration file when you e-mail us.

ALSO - Because this is a Windows program, the initial download is quite large.  The program itself is not so big.  If you are installing for the first time, you will need to download the full version. If you are updating your previous install, you can download only the program and overwrite your existing copy.

AND - The manual and sample configuration files for Entrer Trois are still relevant for E4 though updated versions of both are forthcoming.

CALIPERS - Looking for a set of calipers?  We highly recommend the Mitutoyo electronic calipers (150mm works well for most lithics) with a keyboard wedge.  You can purchase them from Paleo-Tech.
