[REBOL] Remove characters from the end of a string
From: brasilv:tin:it at: 19-Nov-2005 11:48
Hi List, I've got a big problem,
I've a string:
> cmd-iso: "mkisofs -R -J -o %/c/programmi/openpc/backup/back.iso %"
> cmd-iso: append cmd-iso selected-dir
(I'm quite sure that's a string because the 'type? function told me it was).
I want to remove from that string the last character, that is a "/",
because:
> selected-dir: request-dir ;so I've got a directory name that always ends
with "/" (isn't it?)
But in my script this "/" must be removed, if I make this:
> remove last cmd-iso
I got this error on executing the script:
>** Script Error: remove expected series argument of type: series port
bitset none
>** Where: func [face value][
> cmd-iso: copy cmd-iso
> remove last cmd-iso
> print cmd-iso
>]
>** Near: remove last cmd-iso
Why? Please let me understand why, I need it desperately!!!
Thank you very very much,
Silvia
