OK, but then I need a temporary... Before the backreference trick
I tried the same using more or less what you suggests below, but I
didn't get far because I cannot do $array[EXP][Whatever] (well,
namely I was trying ${array[10]}[1,8], but zsh told me 'no matches
found').
> txt="Some text [particular text] Another text"
> print -l $txt[1,$txt[(i)\[]-2] $txt[(r)\[,(R)\]] $txt[$txt[(I)\]]+2,-1]
How can I do the same without the temporary? I mean, without
assigning to 'txt' or whatever the name of the temporary the result
of $array[EXP]
Thanks for your help :)
