You can implement a poor man's named pipe in DCL by opening the MPA0:
device, which clones that device, and then opening the cloned device.
In DCL, finding out the name of that cloned device is easy, just
translate the logical you used in the open statement:
$ open/read test_input mpa0:
$ my_mpa = f$trnlnm ("test_output")
then
$ open/write test_output 'my_mpa'
or
$ spawn/nowait pipe some_command <'my_mpa'
$ spawn/nowait pipe some_other_command >'my_mpa'
So, if I want to accomplish the same thing in perl, I need to discover
the actual file name associated with an open filehandle. Is this
possible ? Is there some obvious cluetrain in the documentation I
miraculously missed being flattened by ?
Thanks,
