Some time back the Revision Control System (RCS) that I did in conjunction
with Ray Brand was posted to comp.amiga.sources.  It contains a working
popen/pclose pair of functions implemented using the Lattice fexecv function
and the AmigaDos 1.3 PIPE: device.  (it is also available in the fish disk
collection although I don't remember which numbers).  The fexecv function
has problems execing BCPL programs but works fine with any C or Assembler
program I've tried it with.  As to the pipe: device itself, it has been
100% reliable for me.  The popen() function uses the process's address to
create a unique filename for the pipe.

Some while back, I modified the popen/pclose functions to use the arp
library AsyncRun function which seems to be able to exec everything I've
tried (including BCPL stuff).  I'm not sure whether it is worth sending
to comp.amiga.sources but if there is enough interest I could post to
alt.sources otherwise I'll just send via email.

It might be worth noting that I spent some time this past weekend playing
with the Dos2.0 CreateNewProcess and System functions.  They seem to
work fine and I'll be doing a popen/pclose using them this weekend.
