Access to script arguments
[1/6] from: jrdrp:blueyonder at: 24-Nov-2001 1:31
Hi all,
When I try to use/access script arguments they always seem to be set to none
e.g.
do %script1.r /args "testarg"
In script1.r
print system/script/args
gives none

try do/args .....
at your rebol console:
type the following
>> help do
tj

Hi John:
I should have been more clear in my last...
;here's a short example script: name is testargs.r
REBOL[]
print "args:"
args: parse system/script/args none
?? args
;from the command line:
>> do %testargs.r "one two three"
Script: "Untitled" (none)
args:
** Script Error: parse expected input argument of type: series
** Near: args: parse system/script/args none
??
; now try
>> do/args %testargs.r "one two three"
Script: "Untitled" (none)
args:
args: ["one" "two" "three"]
== ["one" "two" "three"]
; does that help?

Hi Tim
Thanks for pointer to me using wrong sysntax i.e.
do %script.r /args "testarg" instead of
do /args %script.r "testarg"
It was very late last night and I guess I was thinking in unix terms -
that's my excuse anyway!
Thanks

better watch the space after 'do,
>> do /args %script.r "testarg"
== "testarg"
this code DOes "/args" which results:
>> do /args
== /args
it then evaluates each of the expressions:
>> %script.r
== %script.r
>> "testargs"
== "testargs"
None of the expressions return an error so the commandline simply returns
the last value. The correct code has no space between "do" & "/args"
>> do/args %script.r "testarg"
** Access Error: Cannot open /C/script.r
** Near: do/args %script.r "testarg"
as you can see, %script.r doesn't exist in the current directory on my
machine, but given a machine where it does exist you should be set!
Enjoy!!

Hi Ammon,
Thanks - I eventually sussed out the error of my ways - no spaces! - I keep
thinking in terms of the Rebol /xxx syntax as specifying parameters. I
*will* remember in future!
