Re: [Bug-apl] strange behavior of --

[enztec]

Hi

the -- is strill required on the cli        script -- arg1 arg2   for 877   i 
don't see what was really changed

script is
#! /usr/local/bin/apl --script --
 ⊃⎕ARG      ⍝ show command line options
)off

script arg1 arg2
unknown option 'arg1'
usage: apl [options]
    options: 


this use to work correctly like all the docs and examples show
