You could add a line in your startup file to add this. For example, if
you don't already have a startup file, create a file, say
my_startup.pro, with something like:

setenv, 'SEADAS=/Volumes/1TBSATDATA/sw/seadas6.2'

If you don't already have a startup file, then you will need to do:

IDL> pref_set, 'IDL_STARTUP', '/path/to/my_startup.pro', /commit

This will tell IDL to execute the commands in the startup file every
time IDL launches (from either the command line or the Workbench).
