By looking for the simplest way to transfer 2-byte data packages from one VM user to another one I came across the OLD stage (and some adjunct) in a PIPSYSF.
Q1: is there some descriptions for OLD? Or more examples than PIPESERV only? Q2: what is the best way to pipe data between VM sessions (restriction: receiver has SET FULLSCREEN ON)? Q3: the PIPSYSF Filter Package at http://vm.marist.edu/~pipeline/pipsysf.html has nothing what meanwhile was moved to the PIPELINE module? Q4: Rob van der Heij's 'Piping through IUCV' from 1994 is still up to date? Or should I go for VMCDATA, VMCLIENT, and VMCLISTEN? Q5: is multitasking and communicate between threads easier than between sessions? (I am MT-untouched.) What I am asking for? I tried to get data via TCP to a FORTRAN program by calling an exec via CSL. The exec does a tcplisten|take|tcpdata|fblock 2|... (and some end-this-pipe-ASAP) what works if I slow down to call this exec not more than every two seconds what is not the foreseen transfer speed. Now I look for a chance to stay with one TCPDATA stage (in a thread or an other session) until the FORTRAN ends.
