As of version 4.3.0 (see Version History)
the environment variable BBAS_ID_DATA_DIR is used to help determine where
BBAS.ID will initially expect files that you wish to open to be located.
When you first open a digitized data file using BBAS.ID, if the environment variable
BBAS_ID_DATA_DIR is set to a value, that value is used as the initial directory for the
open dialog that appears. This means that you will be presented with a dialog
for opening a digitized data file that is initially "in" the specified directory.
This can sometimes make navigating to the directory where your digitized data file
is stored easier.
If the environment variable is not set, then the initial directory for the open
dialog that appears will be your "current" directory.
If you run BBAS.ID by entering the BBAS.ID command from a Command Prompt/DOS window,
then whatever directory was your current Command Prompt/DOS directory will be
your "current" directory for BBAS.ID.
If you run BBAS.ID by clicking on an icon on your desktop or by making a
selection from you "Start" menu, then the "current" directory is determined by the
"Start in" property of the icon or menu selection you used. This property is
usually set to your own "My Documents" directory. If you have not changed the
"Start in" property (or do not know how to change the "Start in" property),
then it will automatically have been set for you to the "My Documents" directory.
Thus your "My Documents" directory will be the initial directory for the
BBAS.ID open dialog.
Once you have opened a file using BBAS.ID, subsequent attempts to open files
(be they digitized data files, event files, or setup files) during the same
running session of BBAS.ID, will start out from the directory of the previously
selected/opened file. At this point, the value of the BBAS_ID_DATA_DIR environment
variable does not matter.
