[REBOL] Sort Problem
From: louisaturk::coxinet::net at: 15-Nov-2001 5:13
Fellow Rebolers,
Why won't this script work? Also, is there an easier or better way to do this?
Sample data is at the bottom of this message.
Important: I want to reverse sort by integer not by string (for example,
sort 115 not "115"). I do not want the word strings considered in the
sort. I want results as follows:
a 115
abraam 73
agaqa 11
abussou 6
agaqe 6
aarwn 5
and so forth. I put the numbers before the words in the script trying to
get it to work, but I really want the numbers after the words. I converted
the database to objects trying to get a sort by integer, but that is not
necessary. I just want a sort routine that will work.
Many thanks in advance.
Louis
