Does each user have his individual load options or are you able to separate them into groups?
# This variable defines the ascii file that contains the load options settings.
# If it is not set, a file called load_options.def in the current directory
# is searched for instead. NOTE: If you set this to a file specification
# that contains spaces, you must enclose the file in quotes, e.g
# UGII_LOAD_OPTIONS="c:\my Data Files\load_options.def"
The above is the default definition for ugii_env.dat
