Summary: Interpreter does not provide STDIN in pipeline

Initial Comment:
The old IBM oRexx interpreter could be used as stage in a pipeline (OS/2, Windows 2000/XP, Linux)
The ooRexx interpreter seems not to work as stage command, example below (Windows XP, Linux SUSE 11.2)
I don't find in the reference/programmer guide whether it is supposed to work.

----------------------------------------------------------------------------------------------------------------
OK as first stage in the pipeline:

uli@ulmo:~> rexx test.rex <temp.dat | more
HELLO
aaa
bbb
ccc
GOODBYE
-------------------------------------------------------------------------------
As second stage in the pipeline, STDIN does not receive input:

uli@ulmo:~> more <temp.dat | rexx test.rex
HELLO
GOODBYE

-------------------------------------------------------------------------------
test.rex:

say hello

do while lines()
   line = linein()
   call lineout , line
   -- say line
   end

say goodbye
-------------------------------------------------------------------------------
temp.dat:

aaa
bbb
ccc
--------------------------------------------------------------------
