The default behaviour of TapeTrack programs can be changed by setting environmental variables.

These variables can be set using the following methods.

set VARIABLE=VALUE

Where VARIABLE is the variable name, and VALUE is the variable value.

To set an environmental variable in the Linux operating system, use the export command.

export VARIABLE=VALUE

Where VARIABLE is the variable name, and VALUE is the variable value.

The TapeTrack Config File that is loaded when each Desktop and Command Line Program is initiated, it can also be used to set environmental variables.

   variables = {
       TMSSLEVELNAMES = "A,B,C";
       TMSSNOLEVELSLOT = "1";
   };
