Save the following as script file in some folder (say c:\my folder).
>From a CMD prompt session in that folder call the script like this:
c:\my folder>"c:\program files\j602\bin\j.exe" -jijx runscript.ijs
"argument one" argument-two
Now check your temp folder for the files test.txt & test2.txt.
======runscript.ijs=====================
NB. call from folder containing runscript.ijs with:
NB.
load 'files'
'hello world' fwrites jpath '~temp/test.txt'
(>ARGV_j_) fwrites jpath '~temp/test2.txt'
args=: 3}. ARGV_j_
('only extra args',LF) fappends jpath '~temp/test2.txt'
(> args) fappends jpath '~temp/test2.txt'
========end script=======================
