Dylan, Could you stick that in the faq? I might find that very useful some day and it would be better for me not to clutter up my local directory? Thanks, Jerry

You may need to do some googling to convert the above for-loop construct into a windows-compatible version. cheers, Dylan _______________________________________________ grassuser mailing list grassuser@grass.itc.it http://grass.itc.it/mailman/listinfo/grassuser _______________________________________________ grassuser mailing list grassuser@grass.itc.it http://grass.itc.it/mailman/listinfo/grassuser
