Two possibilities (there are probably other better ideas that I didn't
think of):

1- if you open AREXX: for writing, then the script gets your process as
	standard input.  If you open it for reading, it gets you as
	standard output.  If you do file functions like examine, delete,
	etc., you get OPERATION NOT SUPPORTED, just like if you tried
	to do it do SER: or PRT:.

2- the AREXX: handler creates a logical file for input or output
	before invoking the script, and the script can choose to use
	the AREXX: files or the ordinary input/output.
