[REBOL] fun with for loops

From: chalz:earthlink at: 1-Aug-2002 22:24

Howdy folks. Got a bit of a difficulty here. Say I'm evaluating a for loop, like reading lines of text from a file. At the beginning of my for loop, I have it check to see if the line is commented, blank, or neither. If it's commented or blank, I want it to just skip to the next iteration of the for loop; however, if it's neither, let it keep going. I would prefer to do this with a simple if [] as opposed to a heavy either [][]... 'break' doesn't do what I need - it kills the for loop entirely, instead of skipping to the next iteration. If I use either [][], I have to do: either condition? [ if true do this ][ if false do these next 20 lines all indented with more indentation yet to come very long lines ] You follow me? It's a coding habit I've picked up from another language. Thanks folks. --Charles
