The shell won't expand variables within single quotes.  Use double
quotes -- CHR("34") -- instead.  (In fact, are the quotes even
necessary here?)

You could also skip putting it in a variable and then using that
variable.  In other words, instead of:

    FI=`command` ; echo "something $FI more stuff" >filename

you can do:

    echo "something `command` more stuff" >filename
