Hm, I see. I seem to remember a special backspace character \b -- would
it work to add that to the string, in the hope of deleting the appended
newline character \n?
I don't think we support \b.
Alternatively, would it work to process strColindices further with:
strsub(strColindices,"\n","")
Seems like it probably should, but in fact the \n escape is
not recognized as a single character to be replaced.
(BTW: I don't understand the help text for strsplit().)
<hansl>
string s = "Three blind mice"
printf "The Trinity is %s in One.\n", strsplit(s, 1)
printf "I dig %s Lemon Jefferson.\n", strsplit(s, 2)
printf "The cat chased the %s.\n", strsplit(s, 3)
