问题
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
