I'm afraid HIC's reply to question about (FLATC '<control-H>)
was somewhat in error - he is right in that the definition of
FLATC corresponds with the number of characters output by PRINC,
but it actually operates by noting the count of number of stored
characters in the string for the PNAME.  But FLATSIZE actually
calls a subroutine of PRIN1, which generates characters for printout,
and then merely counts how many characters were counted.  Neither
of these routines try to outguess whether or not ITS will add
escape characters of its own (PRIN1 of course adds the escape character
slash in front of any control character it is about to print).
My personal opinion is that ITS would have to supply a FLATSIZE
functions for character strings in order to correctly accomplish
what you (KMP) want.
