Currently a rexx program accesses all its arguments
via arg(1), this does not allow the sort of parsing
required by windows programs where for example a
filename can contain spaces.
I believe that there should be 2 alternative methods
of access as follows:
(1) Direct access to the command line as supplied to
regina (no interpretation - double quotes remain as
they were etc).
(2) The equivalent of argv argc in a C program in
which quotes are removed (except where escaped etc).
Maybe accessed via a built in function or stem
Both of the above are quite easy to do in "C" code...
As it is rexx is very dated in this area...
