   \G (double quote). At run-time, return the length, @i{u}, and the
   \G start address, @i{c-addr} of the string. Interpretation: parse

+  \G the string as before, and return @i{c-addr}, @i{u}. Gforth
+  \G @code{allocate}s the string. The resulting memory leak is usually
+  \G not a problem; the exception is if you create strings containing
+  \G @code{S"} and @code{evaluate} them; then the leak is not bounded
+  \G by the size of the interpreted files and you may want to
+  \G @code{free} the strings.  ANS Forth only guarantees one buffer of
+  \G 80 characters, so in standard programs you should assume that the
+  \G string lives only until the next @code{s"}.
