There may be a way to do this already, but it would be nice to be able to execute a logo source file from the command line.
$ echo 'print "HELLO!' > test.lg
$ ucblogo test.lg
$ ucblogo < test.lg
Logo would then execute the script, dumping the output to stdout, and return a status code to the OS indicating if there were any errors during interpretation.
I personally want this for making test scripts, I'm not sure how useful they would be for others.
Also, I'm not sure how graphics would work.
