Re: Reverse the order of an array?

[Steve Talley <stephen.talley@sun.com>]

Thanks Bart.  The best that I had come up with was:

    indexes=({$#osvers..1})
    tmp=('$osvers['$^indexes']')
    osvers=${(e)tmp}

Do you see any way (other than skipping the whole thing :) to simplify
this?

Thanks,

Steve
