Just an extra note that in general, the best ways of passing data are
not via either arguments or environment variables, but rather through
sockets or pipes (both of which come in many variations). On the other
hand, these are superior because they are a mechanism that is much more
difficult to snoop and which can handle much larger amounts of data,
and not because they inherently protect you from quoting issues. Not
that Tcl's particularly prone to such things when the language is used
even remotely idiomatically...
