* " ( [string<">] -- bstring ) or perhaps ( [..] -- str-ptr str-len )

This is the non-portable word which is why the ANSI-committee
on forth has created the two other words, namely S" and C" ,
since each implementation (and in pfe configurable) uses another
runtime behaviour. FIG-forth did return bstring which is the configure
default for pfe.
