You don't really do RPN arithmetic within tcl. You use the expr command (with curly braces) which gives you C-like arithmetic. Grepping through some of my tcl code, it's like this:

set centerX [expr {$pX +($pWidth / 2)}]
or
set idx [expr {$size(1) < $size(2) ? 1 : 2}]

This distinction could be partially eliminated by using tclsh
interactively. Also, algebraic notation can be obtained by piping to
and from bc.
