"printf()"-like functions. Make sure "%s", "%d", and "%%" in your
translated messages match the original.
When you have to change the order of words, you can add "<number>\$"
When you have to change the order of words, you can add "<number>$"
between '%' and the conversion ('s', 'd', etc.) to say "<number>-th

"WEIGHT IS %2\$d, LENGTH IS %1\$d"
"WEIGHT IS %2$d, LENGTH IS %1$d"
The reason you need a backslash before dollar sign is because
this is a double quoted string in Tcl language, and without
it the letter introduces a variable interpolation, which you
do not want here.
A format specification with a '*' (asterisk) refers to *two* arguments
instead of one, hence the succeeding argument number is two higher
instead of one. So, a message like this
"%s ... %*i of %*i %s (%3i%%)"
is equivalent to
"%1$s ... %2$*i of %4$*i %6$s (%7$3i%%)"
- A long message can be split across multiple lines by ending the
string with a double quote, and starting another string on the next
