You need to use the Process_Read event and grab the data as it 
comes in.  Sometimes that's inconvenient and you want to do it 
asynchronously, so I wrote the Backtick function, which you can 
find in Help somewhere, but here it is again:

STATIC PUBLIC FUNCTION Backtick(cmd AS String) AS String
  DIM result AS String
  DIM s AS String
  result = ""
  s = Temp()
  SHELL cmd & " >" & s WAIT
  TRY result = file.Load(s)
  TRY KILL s
  RETURN result
END

It's called "Backtick" because it does more or less what the 
backtick (``) quotes do in the Unix shell and in perl.
