Re: MIA, Ask an Expert: procedure using recursion

["Jeff Knope" <jknope@xxxxxxxx>]

Hi Kate,

A recursive procedure invariably requires some prior setup.  For example:

to GETREADY
make "them [12 2 43 17 64 128]       ;;the material to be processed
make "these []        ;;the repository of the processing
end

then, something like this:

to ADD3 :them
if :them = [] [stop]        ;;criteria for when to quit
make "these lput (first :them) + 3 :these         ;;the action done to each 
element of :them
ADD3 bf :them           ;;repeatedly calls itself, but without the first 
element of the preceding recursion.
end

show :these
15 5 46 20 67 131

And thank you for bringing some common sense to the intellectual property 
question.
--Jeff
