I needed a simple sort for the words in a string and came up with this - hope
it helps others. There are probably better ways to do this so feel free to
share:
/* ------------------ rexx ------------------------ *
| Simple bubble sort for words in a string (array) |
* ------------------------------------------------ */
string = '10 0 1 9 6 2 4 3'
do imx = 1 to words(string)-1
do im = 1 to words(string)
w1 = word(string,im)
w2 = word(string,im+1)
if w1 > w2 then do
if im > 1
then lm = subword(string,1,im-1)
else lm = ''
rm = subword(string,im+2)
string = lm w2 w1 rm
end
end
end
say string
