[REBOL] Using 'call
From: tim-johnsons:web at: 18-Apr-2006 8:21
using REBOL/Core 2.6.2.4.2
If I do this:
res: call "ls *.r"
;; I get output and
>> res
== 0
;; standard return value for system call
but if I do this:
>> listing: copy "" ;; output buffer
res: call/output "ls *.r" listing
>> res
== 204
;; I'm curious about the reason for the value of res.
It is not the length of 'listing, listing is appended with each
call to 'call.
Just curious.
Does this signal an error?
