Thanks.
Somehow, it's not recognizing these functions.
grunt> *DUMP A;*
(a-b-c,1)
(x-y,2)
(z,3)
grunt> *DESCRIBE A;*
A: {code: chararray,v: int}
grunt> *B = FOREACH A GENERATE REGEX_EXTRACT_ALL(code, '(.*)-(.*)');*
2011-01-13 17:35:48,062 [main] ERROR org.apache.pig.tools.grunt.Grunt -
ERROR 1070: Could not resolve REGEX_EXTRACT_ALL using imports: [,
org.apache.pig.builtin., org.apache.pig.impl.builtin.]
It doesn't even like UPPER:
grunt> *C = FOREACH A GENERATE UPPER(code); *
