[REBOL] Re: Multiple Keys
From: ryanc:iesco-dms at: 13-Jul-2001 14:19
What do you mean by "database?"
database: ["col1" "col2" "col3" "xxx1" "xxx2" "xxx3"]
or
database: [["col1" "col2" "col3"] ["xxx1" "xxx2" "xxx3"]]
or something else?
Anyways is this what you want?
if all [not db-mark: find database code not find db-mark chknum] [
insert-data code chknum date amount special
]
