The globals defined when Sage starts up are from sage.all (or sage.all_cmdline or sage.all_notebook). So, in your module, you could do "from sage.all import sgn" along with anything else you need. You could also do "from sage.all import *". --Mike -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
