I imagine that in DrRacket you've used a program #lang datalog and so it uses the `datalog' runtime configuration. In contrast, `racket -l datalog' runs a program ".../collects/datalong/main.rkt" that starts #lang racket/base and so it uses the `racket/base' runtime configuration. _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
