count ( c-addr1 – c-addr2 u ) core “count”
c-addr2 is the first character and u the length of the counted string at c-addr1.
The following word has no useful interpretation semantics (unlike
s") and no interpretive counterpart (unlike [char]), so
you should use it only inside colon definitions (if at all):
C" ( compilation "ccc<quote>" – ; run-time – c-addr ) core-ext “c-quote”
Compilation: parse a string ccc delimited by a "
(double quote). At run-time, return c-addr which
specifies the counted string ccc. Interpretation
semantics are undefined.
