Not a PIPE solution, but you could use the CMS Multitasking queues. There
are drivers to exchange between queues in different virtual machines. Used
via CSL calls, I don't know if Fortran can call CSL routines directly.
I found (REXX) samples as illustration on the VM website. I can dig those
up if you cannot find them.
