\ this word was called PARSE-WORD until 0.3.0, but Open Firmware and |
|
\ dpANS6 A.6.2.2008 have a word with that name that behaves |

: word ( char "<chars>ccc<char>-- c-addr ) \ core |
|
\G Skip leading delimiters. Parse @i{ccc}, delimited by |
|
\G @i{char}, in the parse area. @i{c-addr} is the address of a |
|
\G transient region containing the parsed string in |
|
\G counted-string format. If the parse area was empty or |
|
\G contained no characters other than delimiters, the resulting |
|
\G string has zero length. A program may replace characters within |
|
\G the counted string. OBSOLESCENT: the counted string has a |
|
\G trailing space that is not included in its length. |
