if you are shure all lines have the same number of columns,
you could [parse my-var »the-split-char«]it,
then putting all in one big block and use 'sort/skip with all its nice
options.
Oh yes, and put the original string after the parts,
so you can extract the stuff with
[forskip sortet-block num-of-cols+original[
append out-lines sorted-block/index-of-original-line
]
hm. you should put only the interesting cols in the block,
if you add the original for exstraction..
