[clug] Pseudo terminals

[Adrian Blake]

Within  a Fortran program I can open up a terminal with a system command like:   call system("xterm -T new &" , result)

This creates a device   /dev/pty/x   x is some number

I then  would like to be able to direct output to that device:  OPEN (UNIT=15, FILE="/dev/pts/x", STATUS="OLD", ACCESS="STREAM") , 
but how can I determine the value of x?

I could do : ps -ax | grep pty/     and then pick the greatest numbered pty.  Clumsy under program control.

Any suggestions?
