[Oorexx-users] Od behaviour when passing the ? symbol as an argument

[Maurice <ma...@bc...>]

Just come across weirdly inconsistent results when passing "?" as an 
argument. What have I overlooked, I wonder...

Given the test program called 'odd':

  #!  /usr/bin/rexx
  parse arg given .
  say "/"given"/"

then using  ooRexx-4.1.1.opensuse1140.i586.rpm on Linux Mageia-3, I 
get the following inconsistencies between laptop and desktop machines 
using the same version of ooRexx and Mageia-3:

Laptop:

  $rexx ~/rx/odd ?
  /?/
  $ rexx ~/rx/odd ??
  /rx/
  ]$ rexx ~/rx/odd ???
  /bin/

Desktop:

  $ rexx ~/rx/odd ?
  /A/                <-----------------Note!
  $ rexx ~/rx/odd ??
  /rx/
  $ rexx ~/rx/odd ???
  /bin/

Questions:
  (1) With one "?", why do laptop and desktop yield different results?
  (2) Why the unexpected results with strings of multiple "?"s?
  
What characteristics of "?" as an argument have I accidentally hit?!
