If you need to set multiple parameters in the User Options, you can use whitespace (spaces, tabs, and newlines) as delimiters to separate parameter statements. For example:
enable_procedural_cache off error_color_bad_pixel 1 .25 1 declare test constant FLOAT test 2 enable_procedural_cache off\n error_color_bad_pixel 1 .25\n declare test constant FLOAT\n test 2
