Yes, you can certainly use program state as a means of conveying
information, and you can even use global python variables in this manner
even when operating inside of PyMOL command scripts: =20

/obj1=3D"hi"
@ex1.pml

# where ex1.pml contains...

reset
/cmd.zoom(obj1)
/cmd.show("spheres",obj1)

NOTE: a forward slash can be used to explicitly include a line of Python
in a PyMOL script.  Normally it isn't required (since PyMOL commands
fall back on Python "eval"), but it is more efficient because is
bypasses normal parsing.

Again, I view these approaches as best for limited -- real Python
scripts gives you so much more, with very little added burden.
