Hi, Sanjay, Welcome, to REBOL. There are several ways to slice and dice this tomato. I just throw a few out in order to give you some ideas: 1) data: "this is a test no 2" d-blk: parse data none ; yields ["this" "is" "a" "test" "no" "2"] foreach d d-blk [print d] ; yields ;this ;is ;a ;test ;no ;2 print d-blk/6 ; yields "2" type? d-blk/6 ; yields string my-integer: to-integer d-blk/6 ;yields integer type 2 through path notation my-integer: to-integer pick d-blk 6 ;yields integer type 2 through pick notation 2) data: "this is a test no 2" ; now parse as a string ;move through "no" then through ;space then copy next info to my-data ;until reach following space then parse to ;end for parse result of "true" if needed parse/all data [thru "no" thru " " copy my-data to " " to end] print my-data ; yields "2" my-int-data: to-integer my-data ; yields integer type 2 Of course, there are other ways ... If you need a different approach, please feel free to respond. --Scott Jones
