[REBOL] cyclic values

From: rebol665::ifrance::com at: 29-Sep-2002 10:50

Hi List, I want to get values in order from a block, the first value coming again after the last, and this forever. Is there a better way than the one I am using now ? colors: [red green blue] ; I want color to be red, then green, then blue, then red again forever ; the first value is duplicated color: first colors append colors color ; then forever color: select colors color Patrick
