Calico (so far) uses a standard, if not older, version of Boo, so any regular Boo program should work without issue.
To use a Calico module, one needs to import it (which brings the module's items into the current namespace, unlike Python which keeps the names in the Myro module namespace). Also, one must provide all of the arguments for each parameter. For example:
boo---> import Myro boo---> init("COM5", 38400)
