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?!
