Re: --

    Hi Bill,
      
      not sure if I have fully understood the problem. When I run your
      example then I get:
      
      eedjsa@server68:~/apl-1.8/src$
          wslib1/arg_parser_script.apl -- --first=Bill --third=Daly 
        DUMPED 2022-08-02  11:27:51 (GMT+2) 
        NEW )COPY_ONCE workspace: 1 utl
        )COPY utl (file /home/eedjsa/apl-1.8/src/wslib1/utl)
          failed: No such file or directory
        NEW )COPY_ONCE workspace: 1 lex
        )COPY lex (file /home/eedjsa/apl-1.8/src/wslib1/lex)
          failed: No such file or directory
        This workspaces test the arg_parser workspace.  Function
          test_one sets
        up a parser object that expects arguments for --first
          --second and    
        --third and will dispaly the values of those arguments on
          the command 
        line.                                                                
        
                                                                             
        
        The command line must contain an argument '--'  which
          acts as a       
        delimter between the command line arguments passed to apl
          and those   
        passed to this script.  So a test run might
          be:                       
                                                                             
        
        arg_parser_script -- --first=last
          --third=first                       
                                                                             
          VALUE ERROR
        ap∆init[2]  ao←lex∆init
                       ^
      Seems to me like somn workspaces are missing.
      
      Best Regards,
      Jürgen
