call curl from rebol or red doesn't work

Question

On dos cmd this works:

curl.exe -L https://dl.uxnr.de/build/curl/curl_winssl_msys2_mingw64_stc/curl-7.53.1/curl-7.53.1.zip > curl.zip

On red or rebol, following suggestion Cannot read a binary file with red from http, I tried code below but it doesn't work why ?

call {curl.exe -L https://dl.uxnr.de/build/curl/curl_winssl_msys2_mingw64_stc/curl-7.53.1/curl-7.53.1.zip > curl.zip}

I also tried call/wait, it doesn't work either.

Rebol2:

call/output {curl.exe -L https://www.example.com} data: make string! estimated-big-enough-number

Rebol3 (Ren/C branch):

call/shell/output {curl -L https://www.example.com} data: make binary! 0

;; or

call/output [%/path/to/curl "-L" "https://www.example.com"] data: make binary! 0

;;or a poor mans solution as in e.g.

 call {curl -L -k https://dl.uxnr.de/build/curl/curl_winssl_msys2_mingw64_stc/curl-7.53.1/curl-7.53.1.zip  > this-I-want } data: read %this-I-want

Red:

call/output {curl -L -k https://dl.uxnr.de/build/curl/curl_winssl_msys2_mingw64_stc/curl-7.53.1/curl-7.53.1.zip} data: make binary! 100'000

string ? why on earth since it's binary file :) – user310291 Oct 31 '17 at 19:07
@user310291 Can also say **`data: make binary! ...`** – rgchris Oct 31 '17 at 20:26
I modified the answer so that it works for Red and Rebol2 – sqlab Nov 01 '17 at 07:36
My version of R3 is 2.101.0.3.1 and 'call has no refinements for /shell or /output. It only supports /wait. Any tips on how to get capture the data that comes back from cURL? – Edoc Nov 10 '17 at 19:18
You can try a redirect and then read it as in **call "ls -l > this-I-want" data: read %this-I-want** – sqlab Nov 11 '17 at 09:20
