Zack,
  It would go something like this, assuming the strings as being SourceFile$
and OutputFile$, ok?

 cmd$ = COMMAND$        'this gets everything on the command line, following
                        ' the program name (Qcopy)
 p = instr (cmd$, " ")  'find the space between the file names

  if p=0 then            'if command line isn't in the right format
    Print "Usage: Qcopy <source> <destination>"
    print
    end
  endif

 SourceFile$ = left$(cmd$, p-1) 'get string before space
 OutputFile$ = Mid$(cmd$, p+1)  'get string after space

And now, my friend, you're off to the races. Hope this helps. By the way,
learning from other people's programs is one of the best ways to do it.
