Hello Shannon!
On 17-Dic-00, you wrote:

How could EXTRACT decide if User1234 is a word or if User is a
word and 1234 is an integer? Should it treat <WON:387463> as a tag
or as the set-word WON: followed by the integer 387463?
I don't think this is "a simple thing".
Anyway, if you want to search for a certain datatype in a block,
FIND works:
>> find [word 1234 12.23.34] integer!
== [1234 12.23.34]
>> find [word 1234 12.23.34] word!
== [word 1234 12.23.34]
>> find [word 1234 12.23.34] tuple!
== [12.23.34]
Regards,
Gabriele.
