  21. icon-group,
  22.  
  23. I need to extend the functionality of the procedure 'open' when running
  24. a process eg.
  25.  
  26. pipe_in := open ( "/usr/bin/ls", "p" )
  27.  
  28. at present the process can only be opened for reading OR writing. Has
  29. anyone done any development work on enabling the process to be BOTH
  30. written to and read from?
  31.  
  32. I don't if I have to write a new procedure to plug in to Icon 'popen'
  33. for example.
  34.  
  35. Many thanks in advance.
