Subject: Re: RCR for child execution

Some suggestions for names for 
  system2(in, out, err, "command")

exchange(in, out, err, "command")   
# trying to convey idea of two way exchange of data, probably not very
good as really there are 3 streams

or

capture(in, out, err, "command")      
# trying to convey idea of what is happening to in, out and err, but
doesn't give idea that is useful for running external programs like the
word 'system' does.

or

surround(in, out, err, "command")
# similar idea to 'capture' with same drawback of not looking like it
would run an external program

Also all words quite common so could break existing scripts.

All the best,

jon

Hi,

I don't like this notation.  But I like the idea of spawning child
with its stdin/out/err replaced.  It should be something like

  system2(in, out, err, "command")

but it needs better name.
