It would be a lot of temporary files. But look at it this way, you could
set up a file `stdout.dat' manipulated by a DCL script that ran all the
commands in sequence such that:
process n's stdout.dat;N == process n+1's standard input
process n+1's stdout.dat;N+1 == process n+2's standard input
etc...
It'd be marvellous, a different version of stdout for each output stage
of the pipeline. All individually named by version number and _all_ of
them left lying around after the completion of the `pipeline'
The possibilities are endless! :-)
