thanks, [EMAIL PROTECTED], that is what I was trying to achieve. "change" sure does the trick. However, it is interesting that REBOL let you do this: >> blk: [["A" "B" "C"] ["D" "E" "F"]] == [["A" "B" "C"] ["D" "E" "F"]] >> blk/1/1: "X" == ["X" "B" "C"] but not this: >> i: 1 == 1 >> blk/:i/:i: "Y" ** Syntax Error: Invalid word -- :i:. ** Where: (line 1) blk/:i/:i: "Y" >> [blk/:i/:i]: "Y" ** Syntax Error: Invalid word-get -- :. ** Where: (line 1) [blk/:i/:i]: "Y" all I am trying to do is substitute the "value" 1 with :i both are equivalent, are they not? IMHO expressions like these should be evaluatable as they are so convenient to construct and I can think of lots of other advantages for this type of syntax.
