help w/ MicroMundos por favor

[mwforum@xxxxxxxxxxxxxxxxxx (Jeff Knope)]

Hola Daniel,

Can you please help me decipher this. 

These MicroMundos procedures make a marvelously smooth and convincing
depiction of an object in eliptical orbit, coming right at you, rounding in
front of you, and then retreating.  

They are from the Spanish language teacher submittals at the LCSI site Shawn
referred me to,
http://www.microworlds.com/library/contribution/teacher_index.html.  The
program is "Orbita" by Maria Protuguez.

I am unable to distiguinsh MicroMundos primitives from variable names.  There
are neither leading quotes nor dots (except for the variable :radio (radius?)
fed to the procedure Tierra.  I have no idea what ffig, espera, porsiempre,
ad, de, at, lanza, rumbo, ftamano, tamano, or siotro mean.  Are all of these
MicroMundos primitives?  If so, what are there MicroWorlds counterparts?
