[REBOL] [REBOL] stand output handle?

[tjohnson]

Does rebol have a standard output handle like c?
Example : In "C" I can write something like this:
//===
FILE* f;
IF write_to_file THEN
  f = fopen("test.htm","w")
ELSE
  f = stdout;
ENDIF
fprintf(f,"This could be written to the console\n"
  "OR to the console OR as web content");
// thanks in advance

BTW, that's not psuedo-code

I believe I have seen an example where a port was opened to the console
(input and/or output?). It was probably somewhere on rebol.org. I haven't
played with explicit opens to a file. Does rebol keep a "file handle"
entity, or is it just a port?

I'm going to be doing something very similar to this soon, but my 'either
statement will be doing the actual printing/writing, and so for the "stdout"
part I'll just be using a regular 'print.

Redefining 'print would be the simplest way. Something like this:

either write_to_file [
print: function [value] [
write/append %test.htm value
]
] [
print: get in system/words 'print
]

to open a port to the console just use
  f: open [scheme: 'console]
or
  f: open/binary [scheme: 'console]

and to redefine stdout to any port you want:
  system/ports/output: f
