tcl tends to encourage you to think that { } is a block construct, and in
many languages that would close over the values of referenced variables.
It's not. It's a quoted string, and the expansion of $pdv and/or $pv will
be deferred until that quoted string is passed internally to tcl's eval. At
that point, any values for those variables must come from elsewhere.
Use a double quoted string and escape anything that needs it (but
specifically not those variables for which you need the current value).
